The Analemma Page

This website gives both a mathematical and logical explanation of the analemma, which is seen on many maps and globes, and is a record of the path the sun takes through the sky during the course of a year. This figure-eight pattern is due to the Earth's elliptical orbit and its tilted axis. Using animations, equations, and diagrams, the author explains in detail what the analemma is and what causes it to happen.
