01/14/2014 – Ephemeris – The moon will appear to pass Jupiter tonight

January 14, 2014

Ephemeris for Tuesday, January 14th.  The sun will rise at 8:16.  It’ll be up for 9 hours and 10 minutes, setting at 5:27.   The moon, 1 day before full, will set at 7:29 tomorrow morning.

The planet Jupiter will appear close to the nearly full moon this evening.  The moon will pass about 10 of its diameters south of Jupiter around 1 a.m. tomorrow morning.  Until then, Jupiter will appear to the left of the moon.  This is a good time to view Jupiter with a small telescope.  Even binoculars will detect a tiny disk and several of Jupiter’s satellites.  Jupiter is a gas giant planet made primarily of hydrogen.  The clouds contain methane and ammonia whipped into parallel bands by Jupiter’s rapid rotation of nearly 10 hours.  The planet has a noticeable equatorial bulge, which is accentuated visually by its horizontal cloud bands.  Jupiter’s equatorial diameter is 89,000 miles [143,000 km], 11 times that of the earth.  [Jupiter’s volume could hold about 1,300 Earths, but its mass is only about 318 Earths.  Jupiter is less dense than the Earth by a factor of four.]

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

Jupiter and the Moon

Jupiter, the Moon and the bright stars of winter at 9 p.m. on January 14, 2014. By 1 a.m. the Moon will have slipped to be directly below Jupiter. The Moon moves about its own diameter against the stars each hour.  Created using Stellarium.
