05/25/2016 – Ephemeris – Two official evening planets and another also visible in the evening

May 25, 2016 Comments off

Ephemeris for Wednesday, May 25th.  Today the Sun will be up for 15 hours and 10 minutes, setting at 9:15, and will rise tomorrow at 6:03.   The Moon, half way from full to last quarter, will rise at 12:21 tomorrow morning.

Let’s see what the bright naked eye planets are up to.  Jupiter is in the south in the early evening, moving to the southwest.  It will set at 3:01 a.m.  It’s below the stars of Leo this year.  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 is now up at sunset.  It’s above and right of its look-a-like star Antares, whose name means Rival of Mars.  Mars will move due south at 1:17 a.m. and will set at 6:48 a.m.  Mars is still inching closer to the Earth now, only 46.9 million miles (75.6 million km) away.  It will be closest to the Earth next Monday.  Saturn will rise at 9:37 p.m. in the east-southeast.  It’s to the left of Mars, and once it’s been up for an hour is a beautiful sight in any telescope.

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