jovigraphic

Jovi- = [Latin] of Jupiter; graphia = [Greek] description

Jovigraphic means that it describes the planet Jupiter. The jovigraphic coordinate system uses Jupiter's equator for base plane, and uses longitude and latitude for coordinates.

The visible surface of Jupiter is not solid but is made up of clouds. How long it takes for a particular cloud to revolve once around the rotation axis of the planet depends on the jovigraphic latitude: The clouds of Jupiter show differential rotation. Astronomers have therefore defined several different jovigraphic coordinate systems, referred to as "System I" and "System II".
