Question:
What is the velocity of the sun?



Replies:
I am 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/hour). Additionally, the sun (and the solar system) is revolving about the center of the Milky Way at about 150 miles per *second* (that is over a half-million miles/hour!)
