Question

Why does the sun rotate and all other planets in the universe do they rotate?

Answer 1

you are mad sun never rotates only planet rotates around sun

Answer 2

I have never heard of the sun actually spinning as it's a ball of fire. I assume that the planets in our system must rotate as the earth does.

Answer 3

You actually heard it wrongly.

The sun does not rotate.

Answer 4

There may be some confusion between the words rotate and revolve as they are used in astronomy.

Rotate means that the object spins around it's own axis. Both the planets and the sun rotate.

Revolve means that one object circles another. The planets revolve around the sun and rotate on their own axis at the same time. The sun revolves around the center or our Galaxy and rotates around its own axis at the same time... taking the planets along with it in it's revolution around the greater gravity of the Galaxy center.

All three events are caused by gravity. The differences are in where the center of gravity is . Rotation comes from a center of gravity within the objects own mass. Revolution comes from a (stronger) center in another (usually larger, although not neccessarily , as is the case with a black hole)

mass.

Or, as is the case of binary stars that revolve around a shared center of gravity outside of both objects.

Answer 5

Gravity is the simplest answer.

Answer 6

The sun does rotate on its axis-- once every 25 days at the equator--

All of the planets in the solar system rotate-- we can see this in our telescopes and with our space probes. Mercury is a little weird however-- http://cseligman.com/text/planets/mercur...

Planets circling around other stars cannot be seen to rotate-- just too far away. However I would suspect that planet rotation is a universal constant throughout the universe.

Answer 7

Irregularities in the distribution of matter from which stars and planets accumulated is virtually a guarantee that there will be rotation.  Angular momentum is conserved.

Postscript: previous response is wrong.  The sun rotates with an average rate of once every 25 days.

Answer 8

the Moon is in a locked orbit with the earth and does not technically rotate

eventually all planets will stop rotating

a earth day used to be 18 hours shortly after it formed

the reason they rotate is they started out as a disk of spinning gas and debris and it all coalesced into a planet or moon or whatever

the sun does spin but faster at its equator

Answer 9

Yes everything rotates, the sun the moon all of the planets, stars, galaxies, blackholes.  It is pretty universal.

Answer 10

The sun, like all other bodies, rotates (Venus even spins "backward", or the reverse of its orbital motion).  However, unlike solid objects, the sun spins fastest at its equator.
