07/27/2016 – Ephemeris – All the bright planets are now in the evening sky

July 27, 2016

Note: Mercury and Venus are in the evening sky but too low to be easily spotted, even with a Lake Michigan horizon, so I did not cover them in the program below but see the addendum.

Ephemeris for Wednesday, July 27th.  The Sun rises at 6:24.  It’ll be up for 14 hours and 49 minutes, setting at 9:13.  The Moon, 1 day past last quarter, will rise at 1:48 tomorrow morning.

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 11:08 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 1:24 a.m.  The Earth is pulling ahead of Mars so it’s now 65 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 9:53 p.m. and will set at 2:30 a.m.

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