December’s skies offer planetary joy for skywatchers and a casual delight for shooting stars.

a landneighboring planet Mars It becomes bright due to the proximity, but the planet reaches opposition on December 8th.

Our reddish neighbor will be located about 50 million miles from Earth on December 1, according to the Royal Astronomical Society of Canada, and a week later, on December 8, Mars will be opposite the sun From our terrestrial perspective, according to the US Naval Observatory. Think of opposition as “full Mars.” Essentially, this means that Mars will be bright and brilliant at a magnitude of -1.9 in early December.

Mars rises in the east, as the sun sets in the west—and you can find it lounging near the constellation’s pods the Bull the Bull.

While Mars opposition officially occurs on December 8th, you will see the Red Planet very close to Mars the moon On the evening of December 7th. The western United States will see the full moon obscuring (obscuring) Mars. The metropolitan area will see Mars appear to be clinging close to the Moon.

Later in December, our favorite red planet lost a bit of brightness, dimming to -1.4 magnitude (bright) by the end of the month, according to the observatory.

On December 1st, look for the first quarter moon soon Jupiterwhich appears to hang out in the constellation Pisces In the southeastern sky after dusk. Large gaseous planet – magnitude – 2.6, very bright. Catch Jupiter all month long. The fattening Moon also approaches Jupiter on December 28th, and transits the planet by December 29th.

When the sky gets dark after dusk, look up Saturn In the south and southwest in preparation for tuning. The ringed planet stands at the constellation Capricorn At +0.7 degrees, it fainted a bit under urban conditions.

By mid-December, pick up the terrifying friends Mercury And the Venus In the southwestern sky as dusk falls at night. It is very low on the horizon. Mercury’s fleet will be hard to see at -0.6° (exceptionally bright), but Venus will be bright at -3.9° (exceptionally bright). Venus has been hiding near the Sun since October and will climb into the evening sky in January.

The Geminid meteor shower The peak is December 13-14, and astronomers estimate 150 hours into the late evening, according to the American Meteorological Society (amsmeteors.org). You won’t see them all, but if the sky is clear and you avoid streetlights, you can catch several of them. The waning moon rises before 10 p.m., and it may wash out some meteors.

Autumn yields for the winter, like December coup Heralding the change of season on December 21, according to the Observatory. On that date, Washington officially gets 9 hours and 26 minutes of daylight, according to the observatory, creating what’s called the shortest day of the year. We’ll see more sunlight the next day.
