COROT-10b is an enormous exoplanet discovered in 2007 (reported in 2010) by the CoRoT satellite (this satellite preceded the Kepler Space Telescope in searching for planets using the transit method) after 142 days of observation. The planet has a radius of about 0.97 that of Jupiter and orbits its host star, COROT-10, in about 13.4 days. COROT-10 is a K1-type star with a surface temperature of 5075 K. It is slightly smaller in mass and radius (0.89 times the mass and 0.79 times the radius) than the Sun.

The orbital eccentricity of this planet is very large at 0.53 ± 0.04, and its orbit is elliptical, not a perfect circle. It of great interest to understand how such a large planet with such a large orbital eccentricity could exist within our knowledge of the planetary formation process.
