ANALEMMA
Analemma
In astronomy, an analemma is a curve representing the changing angular offset of a celestial body from its mean position on the celestial sphere as viewed from another celestial body . The term is used when the observed body appears, as seen from the viewing body, to move in a way that is repeated at regular intervals, such as once a year or once a day. The analemma is then a closed curve, which does not change.The above text is a snippet from Wikipedia: Analemma
