CoRoT-31 and Its Jupiter-Like Planet
CoRoT-31 is a star 6540 light-years away with a spectral type of G2 IV. It has one known planet. The star is 4.7 billion years old and has a mass of 1.25 solar masses and a radius of 2.15 solar radii. Its temperature is 5700 K. Its reported mass and radius estimates are both larger than the Sun's.
The planet CoRoT-31 b was discovered by transit in 2020. Its orbital period is 4.63 days. Its radius of 16.4 Earth radii makes it Jupiter-like, since that class exceeds 4 times Earth's radius. Its mass is 267 Earth masses, and its mean density is 0.336 g/cm³, 0.0609 times Earth's. Its reported radius and mass estimates are both larger than Earth's.
