Bob Moler's Ephemeris Blog

Ephemeris for Wednesday, July 10th. Today the Sun will be up for 15 hours and 21 minutes, setting at 9:28, and it will rise tomorrow at 6:07. The Moon, 1 day past first quarter, will set at 2:26 tomorrow morning.

Let’s look at the planets for this week. Mercury is now too close to the Sun to be seen. Mars itself is difficult to spot low in the west-northwest, setting at 10:29 p.m. Bright Jupiter will be in the southern sky by 10:30 p.m. With steadily held binoculars a few of the 4 largest satellites of Jupiter can be seen. All four of Jupiter’s largest satellites can be spotted in telescopes. Tonight they will be all arrayed on one side of the planet. Also at 10:30 Saturn will be lower down in the southeast, the brightest star-like object in that direction, but significantly dimmer than Jupiter. The only bright planet left in the morning sky is Venus, which is too close to the Sun to be spotted.

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