10/10/2018 -Ephemeris – Where are the bright planets for this week?

October 10, 2018 Comments off

Ephemeris for Wednesday, October 10th. The Sun will rise at 7:51. It’ll be up for 11 hours and 14 minutes, setting at 7:06. The Moon, 2 days past new, will set at 8:23 this evening.

Let’s look at the bright planets today. Three of them are visible in the evening sky. The brilliant Venus will be just too low to spot, setting 9 minutes after the Sun. The problem isn’t its separation from the Sun, but it is also south of the Sun’s path. Jupiter will be in the west-southwest as it gets dark. The big planet will set at 8:40 p.m. Saturn will start the evening low in the southwestern sky and will set at 11:05 p.m. Mars will be low in the south as the skies darken tonight. and is now 60.5 million miles (97.4 million km) away. Mars will be due south at 9:19 p.m., and it will set at 2:03 a.m. Mars is beginning to pick up speed moving eastward, crossing the constellation of Capricornus this month.

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