Jan Jinings, Age 10, Of Lind, Wash., for his question;

Why does the sun rotate fastest at the equator?

The earth's equator spins around at about 1000 miles an hour. The rotation speed is slomer as we get farther and farther from the equator. At the exact poles, the surface of the earth does not rotate at all. The crust of the earth is solid rock, and the hard shell rotates all in one piece.

The sun also rotates on its axis, and its equator also spins around much faster than the areas nearer the poles. But the sun has no rigid crust of solid rock. It is made of gases which get pulled around by the different rotation speeds. The gases at the sun's equator rotate fastest, because here the sun's rotation speed is the fastest.
