The bright, brilliant planet Venus stars in the December night skies.

In the waning days of November, Venus waltzed with the large Jupiter, but now the planet approaches Saturn. Look to the southwest sky in the early evening to find Venus, which is a -3.9 magnitude object so bright that it seems like a spotlight. Saturn (zero magnitude) sits higher in the heavens, to Venus’s upper left, but it is substantially dimmer than Venus.

By Dec. 7, Saturn and Venus appear much closer, and early next week, Venus appears to skirt the ringed planet. On Dec. 10-11, Venus is within two degrees of Saturn, according to the U.S. Naval Observatory.

Late in the month, the young sliver of a new crescent moon moves toward Venus. Find them in the southwest in the early evenings of Dec. 27-28. The skinny moon gains heft and moves past the glorious Venus by Dec. 29.

If your favorite number is 12, you’re in luck — on the East Coast. The moon reaches its full phase after midnight Dec. 12 at 12:12 a.m. Eastern Standard Time, according to the Royal Astronomical Society of Canada. Officially, the moon reaches full at 5:12 a.m. Universal Time (Greenwich Mean Time), which means that if you’re in Central Time, for example, the moon reaches full phase Dec. 11 at 11:12 p.m.

The Geminid meteors peak Dec. 13-14, according to the American Meteor Society, with a shower as heavy as 150 shooting stars an hour. (The Royal Astronomical Society forecasts the peak at 120 meteors an hour.) Regardless, on Dec. 13-14, the plump gibbous moon beams all night and washes many meteors out. The following night, the moon remains bright. You may see a handful of meteors, at best.

Meteor showers occur when the Earth strikes the leftover dust trails of comets gone by. In the Geminids’ case, it is asteroid Phaethon 3200 dispensing the dust. Earth’s atmosphere strikes the debris and we get a light show.

The Ursids are a smaller meteor shower with about 10 shooting stars an hour that peak Dec. 21-22. The parent comet for the Ursids is 8P/Tuttle, named for Horace Tuttle, a late-19th-century Naval Observatory astronomer.

On the other side of the world, an annular eclipse — the “ring of fire” kind, where the moon doesn’t quite fit in front of the sun — will occur Dec. 26. Astronomy webcaster Slooh.com will feature live feeds of the event starting at 9:30 p.m. EDT on Dec. 25 (Christmas night). The centerline of the eclipse passes through the Middle East, Sri Lanka, Malaysia and Indonesia. For more information, visit eclipsewise.com.

On Earth’s annual trip around the sun, the Northern Hemisphere is tilted away from the sun, so that we reach the winter solstice — when winter officially starts — Dec. 21 at 11:19 p.m. EST, according to the Naval Observatory.
