12/10/2013 – Ephemeris – The bright star Aldebaran, the Follower

December 10, 2013

Ephemeris for Tuesday, December 10th.  The sun will rise at 8:08.  It’ll be up for 8 hours and 53 minutes, setting at 5:02.   The moon, 1 day past first quarter, will set at 2:18 tomorrow morning.

The central constellation of winter, Orion, is in the east southeast at 9 p.m.  Above it is Taurus the bull.  The bright orange star in Taurus is Aldebaran.  Aldebaran appears at the lower left tip of a letter V group of stars lying on its side that is the face of the bull.  Aldebaran isn’t actually part of the group, called the Hyades star cluster.  The cluster is about 153 light years away, while Aldebaran is 65.  The star has an orange hue because its surface is cooler than the sun’s.  However Aldebaran is 44 times larger in diameter, and shines 465 times brighter than the sun.  The name Aldebaran means “Follower”  because it follows the Pleiades star cluster through the skies.  The Pleiades is above right of Aldebaran.

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