Visible planets and night sky guide for August

Mercury will soon go behind the sun

Animation of the sun, with the bright center blocked and large eruptions of glowing gas blasting from its surface.
This image is from the sun-observing SOHO spacecraft. It’s showing activity around the sun from August 19 to 21, 2026. The dark disk blocks the bright sun so that eruptions from the sun are easier to see. We can also see the majestic return of the sun’s innermost planet, Mercury, to our line of sight to the sun. Mercury will be most directly behind the sun, at superior conjunction, on August 27. Then it’ll return to our evening sky. Image via SOHO/LASCO. Image via SOHO/NASA.

August 23 evening: Moon near Teapot

2 positions of the bulging gibbous moon along the ecliptic line, near a teapot-shaped arrangement of stars.
The bright waxing gibbous moon hangs near the Teapot, an asterism in Sagittarius, on the evening of August 23. The direction of the center of the Milky Way galaxy is near the Teapot’s spout. Block out the moon’s light to help spot some of the stars of the Teapot. They’ll set after the middle of the night. Chart via EarthSky.

Heads up! Lunar eclipse coming


Get pointers on viewing the August 27-28 nearly total lunar eclipse from EarthSky’s Deborah Byrd. Watch in the player above, or on YouTube. Prefer to read? Read about the August 27-28 lunar eclipse here.

Late August morning planets: Saturn, Mars, Jupiter

Round sky chart with Jupiter, Mars and Saturn along the curved green ecliptic line running across.
As viewed from the Northern Hemisphere, the late August morning sky will feature 3 bright planets: Saturn shining in the south, Mars climbing in the east and Jupiter hugging the eastern horizon. Note that these planets lie along the path the sun travels in the daytime (the green line on our chart). Chart via EarthSky.

August 25 and 26 evenings: Moon near Capricornus

A nearly round disk, the moon, passes through the middle of a large group of seven dots, the stars of the "arrowhead" shape of Capricornus. They are all above a wavy line, the southeastern horizon.
The bright waxing gibbous moon will pass through the arrowhead shape of Capricornus the Sea-goat on the evenings of August 25 and 26. Try to block out the moon to see some of the stars that form the “arrowhead” shape. You can catch them until around dawn. Chart via EarthSky.

Our charts are mostly set for mid-latitudes in the Northern Hemisphere. To see a precise view – and time – from your location, try Stellarium Online.

August 29 and 30 evenings: Moon near Saturn

A fat hemisphere, the moon, approaches then lies above a dot, Saturn. They are all above a wavy line, the horizon.
The waning gibbous moon joins Saturn on the evenings of August 29 and 30. You can catch them until dawn. Chart via EarthSky.

August evening planet

There are two charts. In the first, a starred dot, Venus, lies above a wavy line, the horizon. A smaller dot, the star Spica, lies far to the upper left of the starred dot. In the second, the small dot, Spica, has moved close to the starred dot, Venus.
In early August shortly after sunset, brilliant Venus will lie low in the west. To its upper left is Spica, the brightest star in Virgo the Maiden. By month’s end, Spica will have dropped much closer to Venus. Venus will reach its greatest distance from the sun on August 14-15. Chart via EarthSky.

Our charts are mostly set for the northern half of Earth. To see a precise view – and time – from your location, try Stellarium Online.

August morning planets

Two charts: In the first, two dots, the stars Castor and Pollux, and a third dot, Betelgeuse, are above a jagged line, the eastern horizon. Another dot, Mars, is above them all. In the second chart, a new dot, the star Procyon, appears above the jagged line. Two dots, Castor and Pollux, have climbed higher above the jagged line. The dot of Mars lies above them all.
In the first half of August, Mars will rise out of the morning twilight and will lie near the star Betelgeuse and the twin stars of Gemini, Castor and Pollux. In the second half of the month, Mars along with Castor and Pollux will have climbed higher above the horizon. The bright star Procyon will also join them above the eastern horizon. Chart via EarthSky.
Two charts: In the first, a dot, Mercury, is right of two dots, the stars Castor and Pollux. They are above a wavy line, the horizon. In the second, the dot, Mercury, is larger than before and is below the two dots of Castor and Pollux. They are all above a wavy line, the horizon.
From the Northern Hemisphere, on the first few mornings of August, Mercury will be near the twin stars of Gemini, Castor and Pollux. By August 10, Mercury will brighten and lie below them, forming a straight line with the twin stars. Chart via EarthSky.
Two charts showing the position of Jupiter in the sky 30 minutes before sunrise. In the first, a small dot, Mercury, is just above a wavy line, the horizon. A larger dot, Jupiter, is just above it. High above them both are two small dots, the stars Castor and Pollux. In the second chart, a dot, Jupiter, lies higher above the wavy line, the horizon.
Jupiter will appear in the bright morning twilight before sunrise around August 12, with Mercury nearby. After August 15, for a few days, Mercury can be seen below Jupiter before disappearing in the bright morning twilight. Then during the second half of the month, Jupiter will steadily climb higher each morning. Chart via EarthSky.
A dot, Mercury, is above a wavy line, the horizon, and below and right of another dot, Mars.
For Southern Hemisphere viewers, Mercury will lie low in the northeast during the first week of August. And Mars will be to its upper left. Chart via EarthSky.

August stars

If you’re out stargazing on any August evening, look for these stars and constellations overhead in the evening sky.

Sky chart showing Cygnus looking like a sideways cross with 2 stars labeled.
If you have a dark sky, it’s easy to observe the edgewise view into our own galaxy – the Milky Way – spanning across the heavens. Need help finding it? Look toward the constellation Cygnus the Swan. You might know this constellation by its asterism, the Northern Cross. The Swan swims along the Milky Way. Its brightest star is Deneb, the Swan’s Tail. Additionally, the constellation Cygnus contains one of the most beloved double stars in the sky, Albireo, which appears blue and gold. Chart via EarthSky.
Star chart showing constellation Lyra with 4 stars and a nebula labeled.
The constellation Lyra the Harp is another summer favorite. It consists of a triangle and a parallelogram. Its brightest star is Vega. Then, look next to it for the famous Double Double Star, Epsilon Lyrae. It’s really 4 stars in all. Chart via EarthSky.
Star chart of a stretched diamond shape with a tail from the wide edge, with labels.
Aquila the Eagle is home to the star Altair, which is one of the corners of the Summer Triangle. In addition, you can use Aquila to starhop your way to the Wild Duck Cluster in Scutum the Shield. Image via EarthSky.
Sky chart with large purple triangle with star Vega at top and small constellation Lyra below Vega.
This chart shows the 3 stars of the Summer Triangle in the evening sky, looking east. Note the size of Vega’s constellation, Lyra. So the Summer Triangle is big! A 12-inch (30 cm) ruler, placed at an arm’s length from your eye, will span the approximate distance from Vega to Altair. And an outstretched hand with thumb and pinky spread will fill the gap between Vega and Deneb. You can see the Summer Triangle in the evening from around May through the end of every year. Chart via EarthSky.

Our charts are mostly set for the northern half of Earth. To see a precise view – and time – from your location, try Stellarium Online.

Have fun exploring the sky!
