You will find two simulations for satellite motion due to the gravitation force between satellite and massive object(center one with cyan color).
Which one is the correct simulation? The one will rotate or another one which does not rotate?
You can pause the simulation. Change the location or velocity of the satellite when velocity vector is visiable, then press 'play' button again. Enjoy it!
