  I'm now wondering if a torus shaped space object is even possible ..

    If they’re not possible then we’re going to have a lot of problems when we try to build rotating space stations for artificial gravity! More seriously though, there is as always math for this. For an object to remain torus shaped it has to resist gravity trying to pull it into a more spherical shape around the centre of mass.
