This is Ephemeris for Wednesday, May 13th. Today the Sun will be up for 14 hours and 46 minutes, setting at 9:02, and it will rise tomorrow at 6:15. The Moon, 1 day before last quarter, will rise at 3:08 tomorrow morning.

Let’s look at the naked-eye planets for this week. Venus is our evening star shining brightly in the west. It will be our evening star for only the next 3 weeks. A tiny crescent can now be seen in binoculars. It will cross between the Earth and the Sun on June 3rd. It will set at 11:43 p.m. It’s only 33 million miles (53 million km) away. In the morning sky there are three planets fairly close together in the south-southeast with the Moon among them tomorrow morning. Bright Jupiter will rise first at 1:35 a.m. Followed by Saturn at 1:50 a.m. Mars, is stretching its lead left of Saturn and will rise at 3:14 a.m. Mars is getting closer to us all the time now, until it closest to us in October of this year.

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