Notes: North is downward and East is to the right. Tethys is involved in an orbital resonance with Mimas such that it completes one orbit for every two orbits of Mimas. The Cassini divison is at a 2:1 resonance with Mimas. When observing Saturn with a telescopes be aware that the background stars can sometimes look like moons. Some of the eight moons may be off the screen.
