  • And one final interesting fact, our sun is actually moving at 200km/s, as is earth, and everything else in our solar system, as it moves around the milky way.

    To be fair, nothing is ever stationary except in very specific frames of reference. I think it’s usually fair to say that the sun is stationary because most of the time when we discuss observations involving the sun, those observation happen within our solar system so the sun is the frame of reference. Otherwise you’d have to constantly point out that a house, tree, mountain or whatever is not stationary, because it moves with the earth.
