Kepler-1312: A Distant Star With Two Known Worlds
Kepler-1312 is a star located 976 light-years away, and it is known to host two planets. The star itself is 2 billion years old, with a mass of 0.99 solar masses, a radius of 0.92 solar radii, and a temperature of 5720 K. Its reported radius estimate is smaller than the Sun's.
Both planets were found 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-1312 b was discovered in 2016 and is classified as a Super-Earth. It has an orbital period of 5.45 days and a radius of 2.1 Earth radii, which is larger than Earth's. Among the listed planets, Kepler-1312 b has the longest year by reported estimates.
Kepler-1312 c was discovered in 2021 and is classified as Earth-like, meaning its radius stays within 1.5 times Earth's radius. It has an orbital period of 1.12 days and a radius of 1.03 Earth radii, which is larger than Earth's. Among the listed planets, Kepler-1312 c has the shortest year by reported estimates and the smallest radius by reported estimates.
