In relationship to the Milky Way would Earth actually be on its side? The Milky Way band moves in the night sky which leads me to believe Earth's rotation is 90 or 180 degrees different from the Milky Way's rotation.

The difference between the celestrial and galactic equators is approximately 63 degrees.

Dear Josh,

Good question. I am not sure just what the solar system's orientation would be relative to the plane of the Milky Way. However, since there is really no up or down or sideways in space, it does not matter much.

Thanks for asking, though.
