Have you ever heard of Lunar Analemma? This digital composite image illustrates the changing position and phase of the moon over the Dali Theater and Museum in Figueres, Spain, during one lunar month. Analemma is generally known as the motion of the Sun in the sky in a complete year. If you follow the position of the Sun at the same time each day, it makes an 8-like trace over the course of a year known as an analemma. The position change is caused by the Earth's motion around the Sun combined with the tilt of the Earth's rotation axis.
