Venus Brightens the Holidays

All the visible planets are ablaze for this holiday season, but none casts light on a dark, wintry evening like Venus.
The brilliant planet can be found low on the southwest horizon after dusk, appearing to beam at -3.9 magnitude (very bright). As December progresses, so does Venus. It climbs a little higher and effervesces through the early evening a little longer. By the winter solstice -- Dec. 22 at 3:04 a.m., according to the U.S. Naval Observatory -- Venus sets in the western sky more than two hours after sunset.
Wise men and women can stand outside on Dec. 24 to catch Venus in the western twilight; if you have a good view of the horizon, you can catch the thin crescent of a new moon below the brightly burning planet.
Mercury, the planet closest to the sun, makes a cameo appearance early in December, skimming along the southwestern horizon at dusk. After the sun sets, this fast-moving planet does not stay visible for long, but for those people with a clear view of the horizon, you can see Mercury and Venus dance a planetary waltz for about the next week.
Mars, sporting its signature rusty red tint, is found high in the south in the evening hours, and sticks around the area half the night. Sky-gazers should have no problem finding it now in the south-southeastern sky as night begins and sets in the west just before midnight. Generally Mars maintains that viewing schedule through the month.
With its brilliant rings beautifully tilted toward Earth at about 25 degrees, Saturn provides a fantastic frolic in the prime-time evening hours. This giant gaseous ball rises in the eastern sky earlier and earlier as the month progresses. Saturn ascends the east-northeastern sky in the 7 p.m. hour, but for practical purposes can be seen better after 8. In the 10 p.m. hour, it is high in the east and becomes due south around 2 a.m.
Watching Saturn only gets better. This planet, found in the constellation Gemini, is at zero magnitude (bright) throughout the month.
On New Year's Eve, Saturn officially reaches opposition. This means that from Earth's perspective, the ringed planet is opposite the sun. In other words, we will have a "full Saturn," and on that evening it rises in the east just as the sun sets in the west.
Another gaseous giant, Jupiter, can be seen easily on the morning side of night. It now rises after midnight in the east and by the end of the December, Jupiter ascends in 10 p.m. hour. It starts the month as a negative first magnitude object (bright) and becomes a negative second magnitude object (very bright) at month's end.
