07/05/2017 – Ephemeris – Our weekly look at the bright planets

July 5, 2017 1 comment

Ephemeris for Wednesday, July 5th. Today the Sun will be up for 15 hours and 26 minutes, setting at 9:30, and it will rise tomorrow at 6:04. The Moon, 4 days before full, will set at 4:22 tomorrow morning.

Let’s take our weekly look at the bright planets. Jupiter is in the southwest as it gets dark in the evening. The bright blue-white star Spica, which pales in comparison to Jupiter, is seen left of it. In even the smallest telescopes Jupiter’s four largest moons can be seen. They shift positions night from to night and sometimes even as you watch. Jupiter will set at 1:25 a.m. Saturn can now be seen in the evening as twilight fades in the south, tonight it’s just left of the bright waxing gibbous Moon. Saturn’s rings are spectacular in telescopes. In the morning sky, brilliant Venus will rise at 3:36 a.m. and be visible until about quarter to 6 tomorrow morning. Mars and Mercury are too close to the direction of the Sun to be seen.

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