# Planets and dwarf planets' tilt and rotation speed

Anyway in this video... to roughly explain the tilts: we think they started out roughly the same in tilt, so either by huge impacts, tidal forces or planetary migration the tilts have been changed. The reason why larger planets tend to spin faster is because they took on more of the Sun-orbiting mass, adding the mass's orbital motion to their spin in the process
