01/12/2012 – Ephemeris – Orion’s Belt

January 12, 2012

Thursday, January 12th.  The sun will rise at 8:17.  It’ll be up for 9 hours and 6 minutes, setting at 5:24.   The moon, 3 days past full, will rise at 9:40 this evening.

Orion’s belt of three stars is one of the most noticeable star groupings in the sky.  There are no other group of three bright stars in a straight line visible anywhere else in the sky.   The star’s names from left to right are Alnitak, Alnilam and Mintaka.  They are actually a bit farther away than the other bright stars of Orion.  Alnilam, the center star is over three times the distance of red giant Betelgeuse above them and over twice as far as blue white giant star Rigel below them.  Alnilam is 375 thousand times brighter than the sun according to the SIMBAD Astronomical Database.  These three stars were also known as Frigga’s Spindle by the Norsemen.  Frigga also known as Freya is the goddess we get the name of the day of the week Friday.

* Times, as always are for the Traverse City/Interlochen area of  Michigan.
