If Exitar isn't fighting back..only to stop himself from falling...well, Superman could pick up several miles of ground around him..fly it up into the stratosphere...heat vision the ground Exitar is standing on til it just crumbles apart...which just sends Exitar falling back to Earth. Supes could then push down on Exitar's chest...keeping him horizontal until he slams back down into the ground....lol...I suppose it could work.
