12/22/2021 – Ephemeris – Let’s search for the naked-eye planets for this week

December 22, 2021

This is Ephemeris for Wednesday, December 22nd. Today the Sun will be up for 8 hours and 48 minutes, setting at 5:05, and it will rise tomorrow at 8:18. The Moon, halfway from full to last quarter, will rise at 8:16 this evening.

Let’s search for the naked-eye planets for this week. Venus will be visible in the southwestern evening twilight by 5:30 tonight. It’s a crescent in telescopes, and even binoculars now. It is moving closer to us, and now appears larger than Jupiter in telescopes. Venus will set at 7:06 pm, 21 minutes earlier than it set a week ago, which means that the Sun is catching up with it faster and faster. It has only 17 days left in the evening sky, It’s now pulling away from Jupiter and Saturn. By 5:45 pm, both Jupiter and Saturn should be able to be spotted in the southwestern sky. Saturn will be dimmer, and to its lower right, halfway between it and Venus. Saturn will set at 8:17 pm, with Jupiter following an hour and a half later at 9:51 pm.

The astronomical event times given are for the Traverse City/Interlochen area of Michigan (EST, UT – 5 hours). They may be different for your location.
