Every constellation rotates completely everyday. So if the Big Dipper is upside down it'll be right side up in twelve hours. Now if you measure at the same time everyday each constellation will be one degree farther along than at the same time the day before and that is the once a year rotation. Your wikipedia reference has a succint description. "Ancient astronomers noticed that the stars in the sky, which circle the celestial pole every day, seem to advance in that circle by approximately one-360th of a circle, i.e., one degree, each day." Otherwise great post. Thanks. Your explanation of constellation rotation is incorrect. Every constellation rotates completely everyday.

Yep, math can be enjoyable if seen in the proper light. I'll try to keep cranking out posts as I can :) Hi Chirag, thanks for the comment! Yep, math can be enjoyable if seen in the proper light.
