APOD 4.8

The Little Dipper
2011 May 14

This is a picture of the very well known and very easily locatable asterism "The Little Dipper".  It is interesting to note that the Little Dipper is NOT a constellation.  It is in the constellation Ursa Minor.  Also, it is important to clarify that perheps the most popularly known star, Polaris, (maybe after Alpha Centauri) is not the brightest star in the sky.  It's actually not even close.  This asterism, or pictographic collection of stars, is easily seen and is circumpolar.  Polaris is actually the denotational star for the top of the sky.  This asterism spans 23 degrees across the night sky.
