Rotation within a vacuum vs rotation with a pressurized environment.

[BAUCE]

common sense tells me that if an object can remain spinning in the vacuum of space for eternity, than placing that same object within a pressurised environment will cause the object to slow to a stop. is there a way for me to calculate the time in which it would take an object to stop rotating within a pressurised environment? the goal would be to achieve the fastest time in stopping an object from spinning.

the goal would be to achieve the fastest time in stopping an object from spinning.

By what means? Changing the shape of the object?

thinking along the lines of trash in space. in order to reach out and grab a piece of debris, either it has to stop spinning, or the rotation must be matched. my thought is that rather than 'grabbing' it, surround it and pressurise the space around it so to stop the rotation.

Sorry, but this doesn't make any sense to me. Why would you do it?

That won't work because of conservation of momentum. We don't know your background. Do you understand "because of conservation of momentum" ?
