CoRoT-21b is a transiting exoplanet reportedly found by the CoRoT space telescope in 2011. Planetary parameters were published in 2012. [3]
It is an extremely hot Jupiter-like planet with an orbital period of 2.72 earth days. Its mass is equivalent to 2.26 Jupiter masses, 1.3 Jupiter radius, and has a density of 1.37 g/cm3.
The planet is experiencing an extreme tidal forces forcing its orbit to decay within 800 million years from now. [4]
CoRoT-21b orbits CoRoT-21 in the constellation of Monoceros. It is a F8IV star with Te = 6200K, M = 1.29 M☉, R = 1.945R☉, and near-solar metallicity. It has an estimated age between 3.6 and 4.6 Gyr.
