07/20/2016 – Ephemeris – The evening planets are moving with the stars to the west

July 20, 2016

Ephemeris for Wednesday, July 20th.  Today the Sun will be up for 15 hours and 4 minutes, setting at 9:21, and it will rise tomorrow at 6:17.  The Moon, 1 day past full, will rise at 9:42 this evening.

Our evening planets are moving with the stars to the west, and setting almost a half hour earlier each week.  Jupiter is in the west in the evening.  It will set at 11:33 p.m.  Binoculars can make out some of Jupiter’s moons, but a telescope is required to see all four bright moons and Jupiter’s cloud features.  Mars starts the evening in the southern sky, moving to the southwest.  It’s above and right of its dimmer look-a-like star Antares, whose name means Rival of Mars.  The planet will set at 1:46 a.m.  The Earth is pulling ahead of Mars so it’s now 61 million miles away and tiny in telescopes.  The ringed planet Saturn is low in the south.  It’s to the left of Mars.  Saturn will pass due south at 10:21 p.m. and will set at 2:58 a.m.

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