2017, August 7: Jupiter and Saturn

Jupiter appears in the western sky this evening.  It appears lower in the sky each evening as it is heading toward its solar conjunction.  It appears near Spica, but the star is hidden by the trees in the image above.  Spica is about 7 degrees to the lower left of Jupiter this evening.  Jupiter is heading toward its final conjunction with Spica in this triple conjunction appearance.

Meanwhile, Saturn — the Ringed Wonder — is in the southern sky.  It is about 13 degrees to the upper left of the star Antares.

Jupiter is slowly moving toward Saturn for a 2020 conjunction.  Tonight the pair is over 60 degrees apart.  Conjunctions of Jupiter and Saturn are uncommon.  They occur in intervals of about 20 years.  During the 2020 conjunction the two planets appear about 0.1 degree apart on December 21.

2017, August: Saturn

Saturn appears in the southern skies during the early evening hours of August 2017.  On August 2, the waxing crescent moon appears about 4 degrees to the upper right of Saturn with the reddish star Antares nearly 13 degrees to the lower right of Saturn.  Saturn is distinctly yellow-orange in color and slightly brighter than Antares.

Later in the month, the moon passes Saturn again.  On the evenings of August 29 and 30, the moon appears about 6 degrees from the planet.  On the first night the moon is the upper right of Saturn on the next evening it is to the upper left of Saturn.

2017, July: Saturn

Saturn, the Ringed Wonder, is low in the southeastern sky after sunset.  While not a spectacularly bright planet, it is a spectacle through a telescope.

The nearly full moon passes 2.5 degrees above Saturn on July 6.  The reddish star Antares is 14 degrees to the right of Saturn.

Every few years, Earth passes Mars. The Red Planet shines brightly in our skies, and prompts many Internet claims that the planet will appear larger than the moon.

In recent history observations of Mars spawned stories of great martian cities and unusual beings.  Mars is a planet that inspires intrigue and speculation.

Once every 15 or 17 years, Mars appears at opposition when it is nearest the sun (perihelion).  Just after midnight (12:13 a.m. Central Daylight Time) on July 27, 2018, opposition occurs and this is near Mars’ closest point to the sun (perihelion).  Opposition is just not one flash-in-the-pan event.  During the evenings leading up to opposition, the Mars grows in brightness and in size, although its planetary globe is not discernible to normal human sight.  A telescope is needed to see the orb of Mars.  More about the appearance of Mars during its 2017-2019 observing year follows.

Morning Appearance

The 768-day observing season begins with Mars’ solar conjunction on July 26, 2017 (7:57 p.m. CDT).

At this time, Mars is behind the sun as viewed from Earth and lost in the sun’s brilliance.  It rises with the sun, lies in the south at noon, and sets around sunrise.  The planet gradually emerges into the morning sky.  This process is slower than most planets as it revolves around the sun every 687 days about half the speed of our planet.

On the chart above notice the scale drawings of the planets’ orbits.  Earth’s orbit is nearly a circle, while Mars’ orbit is more elliptical.  Opposition occurs nearly a year after the conjunction date.   The planets are over-sized on the chart to easily demonstrate their positions.  The yellow line that extends from Earth through the sun defines noon, the morning side of the sky and the evening sky.  The line pointing away from the sun, defines midnight.

This chart was calculated from data by the United States Naval Observatory for Chicago, Illinois, in the Central Time Zone.

The chart shows the rising time of Mars (the red line) compared to sunrise beginning with its solar conjunction (7/26/17) until the time it rises more than 5 hours before the sun (May 23, 2018). The rising time differences for the moon (circles) and other bright planets are included as well as the rising time differences for bright stars that appear near the plane of the solar system (ecliptic) where the planets appear to move in the sky.  The time differences are included for Civil Twilight, Nautical Twilight and Astronomical Twilight.  These events occur in the eastern sky, except for the Saturn sets and Jupiter Sets circles.  Those planets are setting in the morning western sky.

Mars is hidden in the sun’s glare until late August, although it can be found with optical assistance.  Mars appears near a celestial object when its rising line crosses other celestial objects’ rising lines or when the Mars rising line appears near a circle indicating the rising of the moon.  During this morning appearance, the Red Planet has conjunctions with Mercury, Venus, Spica, Jupiter, Antares and Saturn.

As it rises and sets from Earth’s rotation, it rises earlier each morning from our revolution around the sun and its revolution around the sun.  At its solar conjunction we are 180 degrees from Mars and are moving nearly twice its speed, so it’s a slow catch-up game.  Meanwhile the other celestial objects rise earlier from our revolution around the sun, except for Mercury, the moon and Venus.

Mars-Mercury Conjunction

As Mars emerges from the sun’s glare, it is dim in our skies.  In late August and early September it appears near Regulus, Mercury. Venus and the moon.

On the morning of September 16, Mars and Mercury appear very close together, less than 0.2 degrees apart!  The pair is only 17 degrees from the sun and near the horizon when the sky begins to brighten.  Mars is over 240 million miles away, appearing as a not-so-bright star in the morning sky.

Our view on this morning puts Mercury and Mars, in conjunction, near the eastern horizon with Regulus 7 degrees above Mars with Venus and the waning crescent moon higher in the sky.  Find a clear horizon and use binoculars.  This view shows them one hour before sunrise, about the time of nautical twilight, when the horizon is first distinguishable.

Venus-Mars Conjunction

Mars and Venus were last in conjunction on November 3, 2015 when they were about 3/4 degree apart.  As with the last conjunction the 2017 conjunction occurs in a sky full of planets as noted here.  Also note that these conjunctions occur farther east along the solar system’s (ecliptic) plane.

As Venus heads toward its solar superior conjunction, it passes Mars on the morning of October 5.  On the rising chart above notice that the Venus rising time(the green line) diminishes during the autumn of 2017.  Mars’ separation from the sun has grown to 23 degrees.  Earth is slowly catching Mars, yet opposition is months away.  From this scale drawing notice that Venus’ orbit is closer to Earth than Mars.

The separation of the pair is about one-fourth of a degree.  This would be spectacular conjunction if Mars were brighter.  However, Venus-Mars conjunctions only occur when Mars is far away from our planet and near the sun (where Venus appears).  For more about the appearance of Venus, see this article.  The planets are close for a few mornings before and after this close passing.

The moon moves through its orbit about every 27 days and its cycle of phases nearly every 30 days.  The circles on the chart indicate the rising times of the moon.  If a moon circle appears near a planet or star on the chart, there is a good chance they are together in the sky.  For example on October 17, the moon circle appears with Mars and Venus (the green line) rises less than an hour later.

The view of that morning is a close appearance of the waning crescent moon and Mars (1.3 degrees) with Venus 7 degrees to the lower left of Mars.

Mars-Spica Conjunction

Mars then slowly lumbers eastward compared to the starry background, moving eastward along the solar system’s ecliptic plane.  Earth is slowly catching up to the Red Planet and it has brightened only slightly since its first morning appearance.

On the morning of November 30, Mars passes slightly more than 3 degrees from the star Spica. The pair is close for a few days before the closest pairing.  Jupiter began its morning appearance in late October is now about 16.5 degrees to the lower left of Mars.  Watch Mars catch up with Jupiter during the next six weeks as the two pass early in 2018.

Jupiter-Mars Conjunction

By early 2018, Mars is now nearly 60 degrees from the sun, rising about 4.5 hours before sunrise, nearly 45% brighter than when it first appeared in the morning sky, and about 180 million miles from Earth.  Earth is slowly catching.  Recall, that Mars moves at about half the speed of Earth, so it’ll over six months to catch Mars from this point.

On a few mornings around January 7, 2018, Mars passes close to Jupiter near the stars of Libra with the star Antares nearly 23 degrees to the lower left of the planetary pair.  Jupiter is over three times farther away than Mars, yet it outshines the nearer planet by 20 times.  Jupiter’s brightness is from its enormous size compared to Mars and its highly reflective cloud tops.  Jupiter’s clouds reflect nearly 40% more sunlight than Mars’ rocky and dusty surface.  Since it is over 3 times farther away than Mars early in the new year, it receives only 11% of the sunlight that reaches its red neighbor.  Jupiter is highly reflective and much larger, yet it receives much less sunlight than Mars.

Future Jupiter-Mars Conjunctions

Jupiter and Mars are in conjunction in spans of 26-27 months.

The next conjunction is March 20, 2020 when the two planets are about 0.7 degree apart when they rise in the morning sky before the beginning to twilight.  A close conjunction occurs (0.3 degrees) on August 14, 2024 when the two planets rise in the northeastern sky after 1:30 a.m.  The conjunction occurs among the bright stars of Taurus  near Aldebaran and the Hyades.  A conjunction slight closer than the 2018 conjunction (0.2 degree) occurs on December 1, 2033.  The planets appear in the evening sky in front of the dim stars of Aquarius, setting at about 10:30 p.m.

Mars-Antares Conjunction

During the next 30 days, Mars continues to ramble eastward among the stars and growing nearly 40% in brightness.  On the morning of February 10, Mars passes 5 degrees from the star Antares.  Jupiter is 17 degrees to the upper right of Mars and the waning crescent moon is 14 degrees to the lower left.  Mars is the Roman name for this planet.  The Greeks called it Ares.  Antares is sometimes called the “Rival of Mars.”  When are both are in the sky the resemble each other in brightness and color.  Another way to consider this is the prefix “Ant,”  sometimes meaning against: Antares = Against Mars.  Yet another way is to think that “Ant” can be replaced with “Not:” Not Mars.  This star is Antares, not Mars; it’s not Mars.

Mars at Quadrature West

By late March, Mars is well past Jupiter with an upcoming conjunction with Saturn, yet still in the morning sky.  It has grown in brightness nearly 2.5 times since the beginning of the year.  On March 23, it is 90 degrees from the sun (quadrature), rising about four hours, twenty minutes before sunrise and shines from the southern skies at sunrise.  Earth is beginning to approach Mars, still 110 million miles away, but the opposition is still 3 months away.

Mars-Saturn Conjunction

Mars continues eastward march against the starry background, reaching Saturn on April 2, 2018 when the two planets are about 1.25 degrees apart.  The Red Planet is slightly brighter (about 23%) than Saturn.  The color contrast is distinct, with Saturn’s pale yellow-orange color distinguished from Mars’ red-orange hue.  This conjunction occurs north of the main stars of Sagittarius, also commonly called “The Teapot.”

Mars Retrograde

After the Saturn conjunction, Mars continues to move eastward compared to the stars, yet it rises in the east and sets in the west as Earth rotates.  It moves away from the region of the Tea Pot toward the stars of Capricornus.  On June 26, Mars stops its eastward motion among the stars and begins to appear to move backwards, retrograde.  Since its conjunction with Saturn, this brightness grows over times and its distance diminished 2.5 times.  For the next month, Mars continues to retrograde as it reaches opposition, rising in the east at sunset and setting in the west at sunrise.  Its brightness grows another 20%.  Because Mars’ orbit is noticeably elliptical, opposition night is not the closest night.  Four nights later Mars is closest it has been since August 28, 2003.

This chart shows the close opposition of Mars.  The planet orbits are to scale, the planet sizes are not to scale.  Mars appears as a bright star at opposition.  (It will not appear the size of the moon.)  The “midnight” indicates that Mars is south at midnight, opposite the time when the sun is south.

On Opposition night the full moon appears about 7 degrees from Mars as they rise in the east at sunset.  On the evenings around opposition, Mars outshines all other stars and planets except Venus, although the moon is 10000 times brighter than Mars.

Other close historic perihelic oppositions:

  • August 10, 1971, 0.376 A.U. (1 A.U. is about 93 million miles, the average earth-sun distance)
  • August 18, 1845, 0.373 A.U.

The next perihelic opposition is September 15, 2035 (0.382 A.U.).  The next Mars opposition is October 13, 2020 (0.42 A.U.).  A more extensive list of oppositions appears at the end of this article.

Mars continues to retrograde until August 27, dimming slightly as it moves westward motion against the stars.

Resuming its eastward motion, Mars dims considerably, nearly 2.5 times as our planet now moves away from it as the last date displayed on the chart is displayed (October 13, 2018).

For more details about the opposition, see this article.

Mars in the Evening Sky

After opposition, Mars is in the eastern sky during the early evening, in the south in the middle of the night and setting in the west well before sunrise.

On December 1, 2018, as Earth pulls away from Mars, it is 90 degrees east of the sun, now in the evening sky.  (The angle Sun-Earth-Mars angle is 90 degrees.)  It appears in the southern sky around sunset.

On New Years Day 2019, Mars is in the southern sky after sunset and setting in the west around midnight.

In early March 2019, Mars “appears” on the evening sky chart showing when planets, the moon (circles) and bright stars near the ecliptic set after sunset.  This chart refers to activity in the western sky after sunset.  The Jupiter rises and Saturn rises circles refer to activity in the eastern evening sky.

Mars continues to move eastward compared to the stars, now much dimmer than it was a few months ago.  On the evening of March 11, 2019, the moon appears about 7 degrees to the upper left of Mars.

On March 31, 2019, its eastward motion carries it near the Pleaides star cluster and its brightest star Alcyone.  Away from bright lights, Mars is easily distinguishable from the tiny star cluster.

Through binoculars, the stars cluster stands out.  The contrasting colors of the stars with Mars is easy to see.

During Spring, Mars continues to set earlier each night as it slowly ambles eastward against the stars. By May it is 30 times dimmer than it was at opposition.  While it is one of the brighter celestial objects, Earth is pulling away from Mars making it appear dimmer in our sky.  On May 7, Mars appears near several brighter stars that are prominently displayed in the southern sky during the evening hours of winter.  The moon is 3.75 degrees to the lower left of Mars.  Prominent Betelgeuse, Aldebaran, and Elnath appear in the same region.

Mars begins setting during twilight in early June 2019.  On June 18 Mercury passes 0.2 degree from Mars.  Mercury is over 1.5 times brighter than Mars, yet the Red Planet is over 230 million miles away heading toward its solar conjunction.

Mars setting earlier during twilight each evening becoming a binocular object as it sets in deeper twilight.

As it sets in bright twilight, it passes Pollux and Regulus.  In late August 2019, Venus and Mars pass each other, but the pair sets about 10 minutes after sunset.

Mars reaches its solar conjunction on September 2, 2019, again rising with the sun, is in the southern noon sky, setting in the west with the sun, and ending its 768-day apparition with its perihelic opposition.

A perihelic opposition occurs July 27, 2018.  This close oppositions provides an infrequent opportunity to watch Mars emerge from behind the sun climb into the eastern morning sky.  It gradually increases in brightness to brightly appear at opposition.  Then it slips back into the bright twilight of the sun to complete its dramatic close appearance.

“Imagination is but another name for super intelligence.” — Edgar Rice Burroughs

2017, June: Saturn at Opposition

The Ringed Wonder reaches opposition on the morning of June 15.  At this time our planet is between Saturn and the sun.  On the evenings around opposition, Saturn rises in the opposite direction from the sunset point.  As Earth rotates, it rises higher in the sky each hour.  At midnight it is in the southern sky.  From that time, the planet begins to appear lower in the sky, setting in the southwest as the sun rises in the northeastern sky.

On the evening of June 8, the waning gibbous (just past full) moon appears nearly 3 degrees to the upper left of Saturn.  The reddish star Antares is nearly 16 degrees to the upper right of Saturn.

This is the last opposition of naked eye planets this year.

The three outer planets, which includes Pluto, have oppositions this year, but they are only observed with optical assistance:

  • Pluto,  July 10
  • Neptune, September 5
  • Uranus, October 19

Observers are interested in oppositions because at this time, the planet at opposition is closest to Earth and so the planet’s observable features are easiest to see through telescopes.  The planet is in the sky all night and highest in the sky at midnight.

During an 1894 Mars opposition, Percival Lowell first began to document his later disproved discovery of “canals.”  While remote satellites give close-up images of the distant worlds, there are few more memorable events than seeing Jupiter, Saturn or Mars through a telescope.

In 2018, the three naked eye outer planets appear at opposition within an 80-day period:

  • Jupiter, May 8
  • Saturn, June 27
  • Mars, July 27

As they emerge from their solar conjunctions later in the year, they appear with Venus in the morning sky, including another Venus-Jupiter Epoch Conjunction.  More about these events as they approach.

2017, May: View of Saturn

Saturn rises in the May sky later in the evening.  Early in the month it appears above the eastern horizon around 10 p.m.  While this planet does not dominate the sky in brightness, it is on of the wonders of the sky through a telescope.  Its extensive rings dazzle the eye.

On the morning of May 14, the waning gibbous moon appears about 4.5 degrees from Saturn.  The star Antares, appears 17 degrees to the upper right of Saturn.

On May 1, look for Venus near the eastern horizon, Jupiter near the western horizon and Saturn in the south.

2017: Venus as a Morning Star


Venus on August 13, 2017


Venus last appeared in the morning sky in 2015 and 2016, when it appeared with Mars and Jupiter.


Brilliant Venus zips into the morning sky during April  2017 and dominates the morning sky until year’s end.   During this morning appearance, Venus makes close appearances with the star Regulus and the planets Jupiter and Mars.


This chart shows the rising time of bright planets, the moon, and stars near the planets’ orbital plane (ecliptic) compared to sunrise as calculated from U.S. Naval Observatory data for Chicago, Illinois in the Central Time Zone.  Additionally, the times when Jupiter sets and Saturn sets are charted compared to sunrise.  On April 7, Jupiter is at opposition and it sets in the west at sunrise.  The time differences are also displayed for Civil Twilight, Nautical Twilight and Astronomical Twilight.  At Astronomical Twilight, the sky is as dark as it gets naturally.

The rising time of Venus is represented by the green line on the chart.  It enters the chart in mid-March, reaching its maximum rising time difference during the summer, and leaves the sky in early 2018.  Notice that during the summer months of this appearance of Venus, the brilliant planet rises well before the beginning of twilight.  It stands low in the eastern sky as the sky brightens.

As Venus appears earlier in the morning sky, Jupiter shines brightly in the western sky, until about May 20 when Jupiter sets as Venus rises. (Notice on the chart, Jupiter sets line crosses the Venus rises at May 20.)  After this date Jupiter sets before Venus rises.  Similarly, Saturn, while not as bright as Jupiter or Venus, reaches opposition on June 15, setting in the west as Venus rises in the eastern sky.  Venus appears in the eastern morning sky and Saturn appears in the western sky until about July 25 when Saturn sets as Venus rises.  After this date Saturn sets before Venus rises.

Later in the year, Venus appears near Regulus.  This occurs near the date when the rising lines of Regulus and Venus intersect.  The same occurs for Mars, Spica, and Jupiter.  As Venus moves back into bright sunlight later in the year, it appears near Mercury, Antares and Saturn, although they appear together during bright twilight and out of view for most observers.

Venus has a close conjunction with Mars on October 5, followed by a very close (Epoch) conjunction with Jupiter on November 13.

The moon passes Venus each month, as our nearest celestial neighbor moves through its celestial path.  Two dates (May 22 and July 20) are especially noteworthy when Venus and the moon appear about 3.5 degrees apart.

Inferior Conjunction


Venus moves between Earth and Sun on March 25, 2017; this is known as inferior conjunction.  Since Venus has a shorter orbital path and faster speed, it quickly moves into the morning sky.  The red line on the chart shows the division between morning and evening.  The line pointing from the earth to the sun indicates noon.  So at inferior conjunction, Venus rises with the sun, appears in the south at noon, and sets in the west at sunset.

Venus does not appear in the sky at midnight at mid-northern latitudes.  That occurs when a planet is opposite the sun in the sky as seen from Earth.  On the chart notice that the midnight line does not point toward Venus.

As Venus reaches this inferior conjunction, it passes above the sun.  Because it is north, above the sun, it rises earlier than the sun.  On conjunction morning it rises about 40 minutes before the sun.  On the rising chart above, it first appears on the chart on March 14, 11 days before it reaches conjunction!

Venus was last at inferior conjunction on August 25, 2015, 589 days between inferior conjunctions.

Greatest Brightness

The planet rapidly moves into the morning sky, rising earlier each morning.  It is very close to our planet and sparkles in the morning sky.  The brightness is from the proximity of the planet to Earth, its highly reflective clouds and the phase of the planet.  (Yes, Venus shows phases when viewed through a telescope.)  At this time Venus is about 170 times the moon’s distance, relatively close compared to other planets.


From April 15 through May 13, Venus appears brightest in our skies, with the mid-point on May 1, 2017.  This is shown with the GB (greatest brightness) designation on the rising chart above.


Update:  This image is from the beginning of the period of peak brightness.  Venus rises during twilight during maximum brightness during this appearance.


Venus continues to rise earlier each morning. On the morning of May 22, the crescent moon appears about 3.5 degrees from Venus.


Update May 22:  Venus and the moon appear together.

Greatest Elongation


Venus reaches its greatest angular separation (46 degrees) from the sun on June 3.  This is shown by the GE symbol (greatest elongation) on the rising chart above.  It rises about 2 hours before sun near the beginning of twilight.

Venus Dazzles Morning Sky

 Venus continues rising earlier as summer begins.


On July 14, Venus moves past Aldebaran.  The closest approach is about 4 degrees.


The Binocular View

Update: Image of Venus and Aldebaran on July 14, 2017.  Click the image to see the Hyades and the Pleiades.

More striking is the star cluster near Venus and Aldebaran: Hyades.  The Hyades cluster is about 2.5 times farther away than ruddy Aldebaran.  Through binoculars, Venus, Aldebaran and the jewel-like stars of the cluster sparkle against the black velvet of the  predawn sky. Several dozen stars can be seen.

To the unaided eye, the Hyades resemble a check mark or a letter “V” if Aldebaran is included.

Clusters, like the Hyades, are used to refine distance measuring techniques as well descriptions of the lives of stars.  These clusters are thought to form at approximately the same time.  Stars that burn their nuclear fuels faster convert into other stellar forms sooner, such as red giants and red super giants.  From these stellar models, the estimate of the sun’s total lifespan is about 10 billion years.

Over time these clusters break apart; the gravitational forces between the stars are not strong enough to keep the cluster together.  The stars go their own way in their orbital path around the galaxy.

Our sun was likely formed in such a cluster and is now a lone star since it has gone into its own orbit around the Milky Way galaxy.


On the morning of July 20, the crescent moon again appears with Venus.  The pair is separated by about 3.5 degrees.

In early August Venus rises about 3 hours before sunrise and begins to rise later each morning as displayed on the rising chart.  For the rest of the year, it loses about 30 minutes each month.


On September 1, Venus passes about 1 degree from the Beehive star cluster.  Like the Hyades described above, this is a stellar nursery.  It is too far away to be easily seen.  Binoculars will help with the view.  Look around 5:15 a.m. CDT.


In late summer and early Autumn look for Venus and Sirius at the same time.  Both are about the same height (altitude) above the eastern horizon.  Venus stands in the east-northeast and Sirius appears in the southeast.  Only the sun and moon shine brighter than Venus and Sirius is the brightest star in the night sky. See this link to view the last time Venus and Sirius appeared together in the morning sky.


Venus continues its rapid eastward movement as compared to the stars and descent toward the sun’s glow, passing about a half degree from Regulus on September 20.  This pair rises about 2 hours before sunrise.


Over a month later, Venus passes Spica.  The gap is nearly 4 degrees.

Mars Conjunction


The first planetary conjunction of this appearance is with Mars.  On the morning of October 5, Venus passes 0.2 degrees from the Red Planet.  The planets are close on a few mornings before and after the conjunction.

For more about Mars’ appearance during 2017-2019, see this article.

Venus-Jupiter Epoch Conjunction


Another Epoch (close) Conjunction of Venus and Jupiter occurs before sunrise on November 13.  The distance is about .2 degrees.  This conjunction is visible during twilight as the pair rises about 70 minutes before the sun.

The next conjunction between the pair is January 22, 2019 with the next epoch conjunction on April 30, 2022.

For more about the Venus-Jupiter Epoch Conjunction, see this article.

Superior Conjunction

Venus continues its rapid descent into bright sunlight.  Conjunctions occur with Mercury, Antares and Saturn, but they occur in bright twilight, out of the view of most observers.


On January 9, 2018 passes behind the sun at its superior conjunction and reappears in the evening sky.

Lunar Conjunctions

The moon appears with Venus on the following dates:

April 23: 8 degrees


May 22: 3.5 degrees (See description in text)


June 20: 7 degrees


July 20: 3.5 degrees (See description in text)
August 19: 4.5 degrees
September 17: 6 degrees
October 18: 5.5 degrees
