I am trying to make a nucleus electron animation. But I am new to animation it seems.
I can't even get one sphere to revolve around another.
Must I manually place the sphere in it's positions or can I use paths?
About paths, can I use transfrom tools to move the sphere along the path or do I have to adjust the "green" value
that dictates the postition on the curve?
I just want one ball to circle around another one. Like a solar system, well in this case a atom.

Any tips would be helpful!
