Question:
What is the velocity of the sun?


Replies:
I'm not quite sure what you mean by "the sun's velocity". The sun rotates on its axis; a point on its equator makes one rotation in about 25 Earth days, while near the poles it requires about 31 Earth days. So a point on the sun's equator travels at about 4500 miles/hr. (by contrast, a point on the Earth's equator travels at about 1000 miles/hr). Additionally, the sun (and the solar system) is revolving about the center of the Milky Way at about 150 miles per *second* (that's over a half-million miles/hr!)
