To remove from orbit or throw something out of its orbital path; to disturb the circular motion of a celestial body.
From dis- (meaning to reverse or undo) + orb (from Latin orbis, meaning circle or ring). The prefix dis- was added to the verb 'orb' (to move in an orbit) to create the opposite action.
While this word appears in historical dictionaries, it's rarely used today because modern astronomy uses more precise terms like 'destabilize orbit' or 'eject from orbit.' It's a ghostword—technically real but mostly forgotten by time.
