09/24/2014 – Ephemeris – Where are the bright planets this week?
Ephemeris for Wednesday, September 24th. The sun will rise at 7:31. It’ll be up for 12 hours and 4 minutes, setting at 7:36. The moon is new today, and won’t be visible.
Let’s take our weekly look at the bright planets. Mars and Saturn are in the southwestern sky at 9 p.m. with Saturn to the right and a bit below Mars by 17 degrees, about the two widths of your fist held at arm’s length. Saturn will set at 9:38 p.m. Saturn is in Libra, while Mars is in Scorpius. Mars is closing in on a star that has the identical color, and this year the same brightness, its rival Antares. Indeed that’s what the star’s name means: Ant as in anti, Ares the Greek god of war, and the counterpart of the Roman Mars. They will be closest Saturday. Mars will set at 10:13.. In the morning sky brilliant Jupiter will rise in the east-northeast at 3:23 a.m., while Venus, will rise in the east at 6:51 a.m. only 42 minutes before the sun. I’m not sure you’ll see it.
Times are for the Traverse City/Interlochen area of Michigan. They may be different for your location.

Mars is closing in to a star that has the identical hue, and this year the same brightness, its rival Antares.
