This is the part that fascinates me about astrophysics. Everyone always thinks of the sun just sitting there and we’re rotating around it, but in fact we’re all moving relative to the Milky Way at extreme velocities... you would think that eventually the “drag” of dust would cause the planets to fall behind.... and how did they all get up to momentum together .... and why aren’t all those asteroids and Kupier belt objects falling behind....
It’s just fasicinating such a complicated creation.
