Kepler-10 and Its Three Planets

Kepler-10 is a star located 605 light-years away. It is 11.9 billion years old and has a mass of 0.895 solar masses, a radius of 1.06 solar radii, and a temperature of 5630 K. Its reported mass estimate is smaller than the Sun's, its reported radius estimate is larger than the Sun's, and its reported temperature is cooler than the Sun's. Three planets orbit this host.

Kepler-10 b and Kepler-10 c were both discovered by transit in 2011, while Kepler-10 d was discovered by radial velocity in 2023. Kepler-10 b is classified as Earth-like. It has a mass of 3.24 Earth masses, a radius of 1.47 Earth radii, and an orbital period of 0.837 days. Among the listed planets, it has the shortest year by reported estimates.

Kepler-10 c is classified as a Super-Earth. It has a mass of 11.3 Earth masses, a radius of 2.36 Earth radii, and an orbital period of 45.3 days, the second-shortest year among the listed planets. Kepler-10 d has a minimum mass of 12 Earth masses and an orbital period of 151 days, the longest year among the listed planets.

The radii and masses of Kepler-10 b and Kepler-10 c are each larger than Earth's, and Kepler-10 d's minimum mass is larger than Earth's. Kepler-10 b's mean density is 5.62 g/cm³, 1.02 times Earth's, while Kepler-10 c's is 4.76 g/cm³, 0.864 times Earth's.
