08/15/2014 – Ephemeris – Jupiter and Venus will appear to cross paths Monday morning

August 15, 2014 Comments off

Ephemeris for Friday, August 15th.  The sun rises at 6:45.  It’ll be up for 14 hours and 2 minutes, setting at 8:47.   The moon, 2 days before last quarter, will rise at 11:33 this evening.

Over this weekend the planets Venus and Jupiter will be seen to approach each other.  In reality Jupiter is five times the Earth’s distance behind the sun, while Venus is about 70 percent of Earth’s distance behind the sun.  Most of the motion against what stars can be seen after 5:30 a.m. will be Venus, being dragged by the sun plus its own orbital motion toward the east.  Jupiter is moving eastward too, but is taking its sweet time of 12 years to orbit the sun.  The planets will cross, or be in conjunction at about midnight Monday morning, before they rise.  By the time they will rise around 5:12 a.m. the two planets will be half the width of the Moon apart, slightly farther apart than they were at midnight.

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