Astronomers Find 'Backward' Planet Orbiting Its Star The Wrong Way
Astronomers have found an exoplanet, GJ 3090 b, orbiting its small red star in a retrograde direction — backwards relative to the star's spin. Planets normally form from the same protoplanetary disk as their star and inherit its rotation, so a backward orbit is a genuine puzzle, since flipping it would take enormous energy. The team hopes the oddball world will clarify how planets assemble around red dwarfs, the galaxy's most common stars.
