03/16/2015 – Ephemeris – The bright star Aldebaran

March 16, 2015

Ephemeris for Monday, March 16th.  The Sun will rise at 7:53.  It’ll be up for 11 hours and 56 minutes, setting at 7:49.   The Moon, 3 days past last quarter, will rise at 5:57 tomorrow morning.

The constellation Orion, is in the south-southwest at 9 p.m.  To the right of it, in the southwest is Taurus the bull.  The bright orange star in Taurus is Aldebaran.  Aldebaran appears at the upper left tip of a letter V group of stars that is the face of the bull.  Aldebaran isn’t actually part of the group, called the Hyades star cluster.  The cluster is about 151 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 518 times brighter than the sun.  The name Aldebaran means “Follower”  because it follows the Pleiade star cluster through the skies.  The Pleiades are to the right of Aldebaran.

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