CoRoT-20c is a brown dwarf-massed substellar companion found by the HARPS radial-velocity search terrestrial telescope. It orbits CoRoT-20, a G2V star in the constellation of Monoceros. It has an effective temperature of 5,880 K (5,610 °C; 10,120 °F), a mass of 1.14 M☉, a radius of 0.92 R☉, and an above-solar metallicity. This is a young planet, with an estimated age between 0.06 and 0.14 Gyr.[2]
