    The particles in the cloud of gas that the Sun formed from were moving as they collapsed. This movement remains as a property known as angular momentum. Angular momentum cannot be destroyed so the Sun reflects the earlier particle movement by spinning.

    could angular momentum ever be stopped though?

    Yes, by friction. In fact, there is a problem of losing angular momentum during the star formation process. If it would have been conserved fully, the sun would rotate much faster. So, there must be processes involved that transform the angular momentum into something else.

    Possible solutions are friction with the remaining gas and dust in the forming planetary system as well as magnetic fields. Those fields are tied to the sun's plasma and the the inter-planetary medium and thus act like brakes.

    Angular momentum can also be exchanged between rotating objects. For instance, the angular momentum of the sun's rotation can be transformed in the angular momentum of the revolution of the planets around the sun. By this, they gain speed and increase their distance. This is exactly what happened and is still happening between the earth and the moon.

    wow i was just reading that different parts of the sun rotate at different speeds depending on there closeness with the poles! Thats pretty amazing!
