Big planet, tiny star

Part of the quest to find supermassive black hole origins.

Comparison of GJ 3512 to the Solar System and other nearby red-dwarf planetary systems. Planets around a solar-mass stars can grow until they start accreting gas and become giant planets such as Jupiter, in a few millions of years. But we thought that small stars such as Proxima, TRAPPIST-1, Teegardern’s star and GJ 3512, could not form Jupiter mass planets. Credit: Guillem Anglada-Escude – IEEC, Spaceengine.org
