Problem Statement:
Model and animate all planets and there moons as given in specification.
Each planet should rotate around itself and also around the sun.
Planet moon should also rotate around itself and around its planet.
Moons should also rotate around sun with its planets.
Use all primitives to create planets and moons.

Record the video.
Post a link to video.
Solution:
I was able rotate moons and planets around its axis in the class.
Then i rotated moons around there planets by creating group for each moon and animating and creating key frames.
Then i grouped each planet and respective groups of there moon.
Then i created key frames for these planet groups by rotating the group around the sun.
For Saturn i also created the ring and make it child of Saturn, so that it also rotates with Saturn.
