The corotation torque is that exerted on a planet’s orbit by material (usually gas) co-orbiting with the planet. This has a very important effect on the orbital migration of planets of less than roughly 50 Earth masses that form in gaseous protoplanetary disks. Recent analysis suggests that very rapid, inward “type 1” migration – caused by tidal interaction between the disk and a planet – may in fact be slowed or even reversed in certain situations due to the corotation torque.
