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 5880K, a mass of 1.14, a radius of 0.92, and an above-solar metallicity. It also hosts another exoplanet, CoRoT-20c.
