Ephemeris: 12/27/2023 – Our last look at the naked-eye planets for 2023

December 27, 2023

This is Ephemeris for Wednesday, December 27th. Today the Sun will be up for 8 hours and 49 minutes, setting at 5:08, and it will rise tomorrow at 8:19. The Moon, 1 day past full, will rise at 5:30 this evening.

Let’s find out where the naked-eye planets have wandered off to this week. Three of those five planets are now visible. Mercury and Mars rise too close to sunrise to be seen. Saturn and Jupiter are the only evening planets. Saturn can be seen moving from low in the southwest to setting in the west-southwest at 9:54 pm. Jupiter will be moving from the high in the southeast to the west-southwest, by midnight and will set at 3:24 am. The Moon, the night after it being full, will be in Gemini tonight, not that any of its stars will be visible, making the sky bright. Venus, the brilliant morning star, will rise in the east-southeast at 4:56, am, and be a brilliant beacon in the morning, shining in the southeast by before the bright morning twilight claims it around 8 am.

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.
