CoRoT-20b is a transiting exoplanet found by the CoRoT space telescope in 2011.

It is a hot Jupiter-sized planet orbiting CoRoT-20. It is a young planet, with an estimated age between 0.06 and 0.14 Gyr. Its density (8.87 g/cm³) is remarkably high for its mass, making CoRoT-20b one of the most compact gas giants.^[3]

Host star

The host star, CoRoT-20, is a G2V star with 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. It also hosts another exoplanet, CoRoT-20c.
