02/03/2021 – Ephemeris – Let’s have a lookout for the naked-eye planets

February 3, 2021 Comments off

This is Ephemeris for Wednesday, February 3rd. Today the Sun will be up for 9 hours and 55 minutes, setting at 5:54, and it will rise tomorrow at 7:57. The Moon, 1 day before last quarter, will rise at 1:03 tomorrow morning.

Let’s have a lookout for the naked-eye planets for this week. It’s slim pickings for the bright naked-eye planets, known from antiquity in our skies right now. Only Mars can be spotted. The rest of them are hanging out in the direction of the Sun and won’t be seen for a month or more. Mars can be found high in the south at 7 pm. It will actually be due south at 6:30 tonight. Mars is increasing its speed eastward through the constellation of Aries the ram, which it’s halfway through, and will set at 1:45 am. Of the outer planets Mars is the fastest, being the closest to the Sun, so unlike Jupiter, Saturn and the stars which rise and set about four minutes earlier each night, Mars rises and sets about a minute and a half earlier each day.

The event times given are for the Traverse City/Interlochen area of Michigan. They may be different for your location.

Planets and the Moon on a single night

Planets and the Moon at sunset and sunrise of a single night starting with sunset on the right on February 3, 2021. The night ends on the left with sunrise on the 4th. I’m afraid that the labels for Jupiter and the Sun overlap, since the planets and Sun are very close. Click on the image to enlarge. Created using my LookingUp program.
