If you put an object in space and spin it really fast would it ever stop spinning?

think about this one..


or if you think it will stop spinning how long will it spin?


... there has to be some air in space, but Very little. based on what i think. and air = frictionIf you put an object in space and spin it really fast would it ever stop spinning?
It will spin for a very very long time.





Random molecules hitting it will cause it to lose a bit of momentum, as will cosmic rays.





A lot depends on the shape. If it is a disc spinning like a frisbee, then random molecules will have little effect, as they will just bounce off the spinning surface, and will not change it by much.

Never stop spinning as long as no resistance.
i dont think so because look at satellites that orbit earth for so many years that remain constant
