EPIC 212737443: A Cool Star With Two Neptune-Like Worlds
EPIC 212737443 is a K3 star located 1,100 light-years away. Its mass is 0.69 solar masses and its radius is 0.673 solar radii, both smaller than the Sun's, and its temperature of 4,680 K is cooler than the Sun's. Two planets orbit this host.
Both planets are Neptune-like and were discovered by transit in 2019. EPIC 212737443 b orbits every 13.6 days and has a radius of 2.59 Earth radii. EPIC 212737443 c orbits every 65.6 days and has a radius of 2.69 Earth radii. Both are larger than Earth. Among the listed planets, EPIC 212737443 b has the shortest year and the smallest radius, while EPIC 212737443 c has the longest year and the largest radius.
