CoRoT-8 and Its Jupiter-Like Planet
CoRoT-8 is a K1 V star located 1050 light-years away, with a mass of 0.88 solar masses, a radius of 0.77 solar radii, and a temperature of 5080 K. Its age carries a reported upper limit of 3 billion years. The star's reported mass and radius estimates are smaller than the Sun's, and its reported temperature is cooler.
One planet orbits this host. CoRoT-8 b is a Jupiter-like planet discovered by transit in 2010. It completes an orbit in 6.21 days, has a mass of 69.9 Earth masses, and a radius of 6.39 Earth radii. Its reported radius estimate is larger than Earth's, and its reported mass estimate is larger than Earth's. Its mean density is 1.48 g/cm³, 0.268 times Earth's.
