05/23/2018 – Ephemeris – Wednesday is bright planet day on Ephemeris

May 23, 2018 Comments off

Ephemeris for Wednesday, May 23rd. Today the Sun will be up for 15 hours and 6 minutes, setting at 9:13, and it will rise tomorrow at 6:05. The Moon, 2 days past first quarter, will set at 3:56 tomorrow morning.

It’s Wednesday again and time to look for the bright planets. Two of them are in the evening sky. The brilliant beacon of Venus will be visible in the western twilight from about 9:35 p.m. until it sets at 11:54. Jupiter will be in the southeast as it gets dark. Jupiter is only out shown by Venus and the Moon. And after Venus sets will have the night to itself as the brightest star-like object until it sets at 5:31 a.m. Binoculars will show it to be not quite star-like in size, that is it will appear as a tiny orb flanked by little star-like moons. Saturn will rise at 11:43 p.m. in the east-southeast. Mars will rise at 1:28 a.m. and is now outshining Saturn, and will, this summer even outshine Jupiter.

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