The Geminids have peaked


Did you see meteors last night? You might see still see some Geminids tonight. It’s a great year for the Geminids! Join EarthSky’s Deborah Byrd to find out more. Watch in the player above or on YouTube.

The predicted peak for the Geminid meteor shower was 3 UTC this morning. You might still see some Geminids from mid-to-late evening tonight until dawn tomorrow morning. A waning crescent moon will rise a few hours after midnight, so it won’t interfere with meteor watching. Plus, the bright planet Jupiter is near the stars of Gemini. Chart via EarthSky.

Venus is nearly behind the sun

Venus is the brightest planet visible from Earth. It left our morning sky some weeks ago. But now the sun-observing SOHO spacecraft can see it near the sun’s glare. Here the sun is behind an occulting disk, blocking out the central glare. The superior conjunction of Venus, when it will be most directly aligned behind the sun from Earth, will come on January 6. It’ll return to visibility in our evening sky in February 2026. Images via NASA/ SOHO.

December evening planets

Here’s an overhead chart depicting 2 bright planets visible in the December evening sky from the Northern Hemisphere. Jupiter will rise in the eastern evening sky and remain visible through dawn. Meanwhile, Saturn will shine brightly in the western sky and set before midnight by the end of the month. The 2 planets lie along the path the sun travels in the daytime (the green line on our chart). Chart via EarthSky.

December morning planets

Sphere chart showing a dot, Mercury, hugging a wavy line, the eastern horizon. Above the western horizon line is a larger dot, Jupiter.
Here’s an overhead chart depicting 2 bright planets in the December morning sky as observed from the Northern Hemisphere. Jupiter will be prominently positioned high in the western morning sky. Mercury will be shining low in the eastern morning twilight. This is Mercury most favorable morning apparition of 2025 for the Northern Hemisphere. But look soon! The elusive planet will gradually disappear from view and be gone sometime around Christmas. Note that the 2 planets lie along the path the sun travels in the daytime (the green line on our chart). Chart via EarthSky.

December 17: Moon reaches apogee

The moon will reach apogee – its farthest distance from Earth in its elliptical orbit – at 6 UTC on December 17, 2025, when it’s 252,476 miles (406,322 km) away.

December 17 morning: Moon, Mercury and Zubenelgenubi

Chart showing a thin crescent shape, the moon, to the right of a dot, Mercury. Above them is another dot, the star Zubenelgenubi. They all are above a wavy line, the horizon.
The thin waning crescent moon will lie near Mercury on the morning of December 17. The bright star Zubenelgenubi will shine nearby. Look for them about 40 minutes before sunrise. Chart via EarthSky.

Zubenelgenubi is the alpha star of Libra the Scales

December 20: New moon

The moment of new moon will fall at 1:43 UTC on December 20, 2025. That’s 7:43 p.m. CST on December 19. New moons rise and set with the sun. Plus, this is the 3rd of 3 new micromoons – or most distant new moons – in 2025. Nights around the new moon are perfect for stargazing, and this one is near the peak of the Ursid meteor shower. See EarthSky’s best places to stargaze.

December 21 solstice

The 2025 December solstice will happen at 15:03 UTC. That’s 9:03 a.m. CST in North America. For us in the Northern Hemisphere, the December solstice marks the longest nights and shortest days of the year. For the Southern Hemisphere, it marks the shortest nights and longest days. After this solstice, the sun will begin moving northward in our sky again. Happy solstice to all!

December 21, 22, 23 and 24 evenings: Looking at holidays lights? Watch for the young moon!

Four different circles showing the increasing phases of a crescent moon on December 21, 22, 23 and 24.
If you’re out looking at holiday lights, check out the pretty young moon. The waxing crescent moon will hang low in the western sky about 30 minutes after sunset on December 21, 22, 23 and 24. It’ll set later each night, but you can start looking for it soon after sunset. Try to catch it during the evening twilight, when it’ll be shining in a colorful sky. Chart via EarthSky.

Ursid meteor shower overnight December 22

The best time to watch for Ursids is before dawn on December 22. In 2025, the new moon occurs a few days before the Ursids peak, so you can watch for them in a dark sky. For the best view, find a dark country site to watch the starry sky. Under ideal conditions you might see 5-10 meteors an hour. Read more about the Ursid meteor shower.

December 26 evening: Moon slips by Saturn

December 27: 1st quarter moon

The moment of 1st quarter moon will fall at 19:10 UTC on December 27, 2025. That’s 1:10 p.m. CST. Did you know you can see an X and V on the 1st quarter moon? Here’s how to see them. A 1st quarter moon rises around noon your local time and sets around midnight. Watch for a 1st quarter moon high in the sky at sundown.

December stars and constellations

If you’re out stargazing on any December evening, look for these stars and constellations high overhead in the evening sky. Give your eyes time to adjust to the darkness. And consider heading to a dark-sky site for the best views of the stars.

Diagram of constellations Cassiopeia and Perseus with arrow from one to the other and bright stars labeled.
In December, look overhead and northward for the M- (or W-) shaped constellation Cassiopeia the Queen. Then, look nearby for the graceful shape of the constellation Perseus and its bright star Mirfak. Plus, Perseus contains the star Algol – known as the Demon Star – because it changes in brightness roughly every 3 days. Chart via EarthSky.
Star chart: constellation Cassiopeia with an arrow pointing to 2 tiny dotted circles, labeled Perseus Double Cluster.
Cassiopeia can also help you find the Double Cluster in Perseus. It consists of 2 open star clusters near each other on the sky’s dome. The 2 clusters reside in the northern part of the constellation Perseus, quite close to the constellation Cassiopeia the Queen. Just scan that area with your binoculars for 2 glittering groups of stars. The breathtaking Double Cluster will be there. Chart via EarthSky.
Star chart: Two-pronged fork-shaped constellation, small cluster at top right, and 2 stars labeled.
The constellation Taurus the Bull is visible in the evening sky now and is close to the easy-to-see constellation Orion the Hunter. It’s home to 2 favorite star clusters and a famous supernova remnant. The Hyades open star cluster forms the V-shaped face of the Bull in Taurus with the bright red star Aldebaran as the fiery eye of the Bull. Another open star cluster, the Pleiades, is nearby. Chart via EarthSky.

December evening planets

A dot, Jupiter, is between two smaller dots, the stars Castor and Pollux and another dot, the star Procyon. They all lie above a horizontal wavy line, the horizon.
Bright Jupiter will rise in the east soon after sunset this month. And it’ll be near the twin stars of Gemini, Castor (the slightly dimmer one) and Pollux (the slightly brighter one). Also, the bright star Procyon is not far away. Jupiter is visible through dawn and will reach opposition – when we fly between it and the sun – on January 10, 2026. It’ll be biggest and brightest then. The moon visits Jupiter around December 7. Chart via EarthSky.
A dot, Saturn, is above another dot, the star Fomalhaut.
Saturn lies in the west in the evening hours of December. It’s the brightest object in that part of the sky, other than the passing moon. And Saturn lies far above a star of similar brightness, Fomalhaut. Saturn reached opposition — when Earth flew between Saturn and the sun — on September 21. The ringed planet rises well before sunset and will set after midnight around December 1st, and then, by month’s end, it’ll set before midnight. Saturn will shine at 1.2 magnitude by month’s end as it lies among the stars of Aquarius the Water Bearer. The rings of Saturn open back up a little this month, going from -0.6 degrees to -1.5 degrees. The moon visits Saturn on December 26 and 27. Saturn will remain visible in the evening sky through February 2026. Chart via EarthSky.

December morning planets

For Northern Hemisphere viewers, Mercury will shine in the bright morning twilight low on the eastern horizon from December 1 until around December 25. It’ll reach its greatest distance from the sun on December 7. This will be the best morning apparition of Mercury for the Northern Hemisphere in 2025. Chart via EarthSky.
