Orientation of the Earth, Sun and Solar System in the Milky Way

[QUOTE="phyzguy, post: 6085519, member: 237160"] I keep pointing out that the sun's motion around the Milky Way is not an "orbit" in the sense that we usually think of it. It is not even a closed curve. Orbits in a central potential like the solar system are closed curves, but orbits in a potential well like the Milky Way's are typically not. Even if the Milky Way's potential were static in time the orbit would not be a closed curve, and it is definitely not static in time. So it is best to think of the sun's motion as an approximate orbit, where each path around the Milky Way is a different curve. [/QUOTE]
