Kepler-252 and Its Two Known Planets

Kepler-252 is a star located 1,240 light-years away. Its spectral type is M0 V, and it has an age of 3.47 billion years. The star's reported mass estimate is 0.7 solar masses, and its reported radius estimate is 0.66 solar radii. Its reported temperature is 4,540 K.

Two planets are known to orbit Kepler-252. Both were discovered in 2014 by the transit method, in which a planet passes in front of its star from our viewpoint and causes a small dip in observed brightness. Kepler-252 b is classified as Earth-like, with an orbital period of 6.67 days and a reported radius estimate of 1.23 Earth radii. Among the listed planets, it has the shortest year and the smallest radius by reported estimates. Kepler-252 c is classified as a Super-Earth, with an orbital period of 10.8 days and a reported radius estimate of 2.15 Earth radii. Among the listed planets, it has the longest year and the largest radius by reported estimates. Both planets' reported radius estimates are larger than Earth's.

The star's reported mass and radius estimates are smaller than the Sun's, and its reported temperature is cooler than the Sun's.
