09/06/2017 – Ephemeris – A look at the bright planets known from antiquity

September 6, 2017 1 comment

Wednesday, September 6th. The Sun will rise at 7:11. It’ll be up for 12 hours and 58 minutes, setting at 8:09. The Moon, at full today, will rise at 8:38 this evening.

Let’s take our weekly look at the bright planets. Jupiter is sinking really low in the west-southwest setting before the end of twilight. The bright blue-white star Spica, which pales in comparison to Jupiter, is seen below it dimly in the twilight. It will pass north of Spica on September 11th. Jupiter will set at 9:36 p.m. Saturn can be seen moving from the south-southwest to the southwest tonight. The reddish star Antares is below and right of Saturn. Saturn’s rings are spectacular in telescopes. The planet will set at 12:29 a.m. In the morning sky, brilliant Venus will rise at 4:31 a.m. and be visible until about 6:45 tomorrow morning. Mars and Mercury follow Venus up in the east rising just before 6 a.m.

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