This website has an animation that shows the difference between sidereal reference frames and synodic.
http://www.sumanasinc.com/webcontent/animations/content/sidereal.html
The motion of the moon is circular about the earth, yet apparently the moon has an apogee length that is 50,000 km further away from Earth than its perigee length.
In this animation have they just assumed a circular orbit for simplicity? How would it look if they didn't make this assumption?
