iliveinaspiralgalaxy: Analemma: If you took a picture of the Sun at the same time each day, would it remain in the same position? The answer is no, and the shape traced out by the Sun over the course of a year is called an analemma. The Sun’s apparent shift is caused by the Earth’s motion around the Sun when combined with the tilt of the Earth’s rotation axis.
