The inertia effect of the bommerang is the same in zero gravity, however the boomerang will not turn becuase there is no air to grab to create angled flight and cause it to return.
it will come back after 24 hrs. lol it will go all the way around
Around what? Its in space.
the moon because of the gravitional pull
Have fun waiting for it, cause it's not coming back
you'd still need to be superman to make it orbit the moon even once
