Solar Analemma

Have you ever heard of an analemma? Most of the time when talking about this phenomena, we are talking about solar analemma, but any celestial object can create an analemma (assuming the proper conditions exist that is). Because of Earth’s tilted axis and its elliptical orbit, the sun changes position in the sky over the course of a year, this causes the sun to follow a curved path through the sky. When the position of the object is recorded at the same time each day over the course of a year, the end result is an analemma.
