APOD 2.7

This weeks Apod is of an analemma which is a figure-8 curve that you get when you mark the position of the Sun at the same time each day throughout the year. 26 separate exposures were recorded to illustrate the regular solar motion. This was done mostly during the 2006 calender year. Each picture was taken at 8 am in the northern New Jersey sky. They were digitally composed with one single foreground later on. Other planets follow the same shape if you were to do this for the sun. Saturn, Uranus, Neptune, and Pluto all have a figure-8 shape. Mars is teardrop shaped whereas Jupiter and Venus form ellipses. For Mercury if done it would form a straight line going east to west.
