Planets of the Solar System.
Listed below are the nine planets that have been identified in our solar system and their respective satellites. The sidereal period of a planet is the amount of time required for that planet to make one revolution about the sun with respect to the stars. The rotational period of a planet is the amount of time required for the planet to perform one complete rotation about its own axis. If the planet rotates on its axis in a manner opposite to that of Earth, the rotation is called retrograde and the number is given with a - sign in front of it.

*The satellites Epimetheus and Janus orbit so closely together that gravitational interactions cause them to regularly exchange orbits.
**The satellites Tethys, Telesto, and Calypso have been determined to be the same distance from Saturn to within current experimental accuracy.
***The satellites Dione and Helene have been determined to be the same distance from Saturn to within current experimental accuracy.
