CoRoT-21b is a transiting exoplanet reportedly found by the CoRoT space telescope in 2011. Planetary parameters were published in 2012.
It is an extremely hot Jupiter-like planet with an orbital period of 2.72 earth days. It has a mass equivalent to 2.26 MJ, a radius of 1.3 RJ, and a density of 1.37 g/cm3.
The planet is experiencing extreme tidal forces, forcing its orbit to decay within 800 million years from now.
