EPIC 212499991: A Cool Star and Its Super-Earth
EPIC 212499991 is a star 924 light-years away with one known planet. The star's reported mass estimate is 0.85 solar masses and its reported radius estimate is 0.752 solar radii, both smaller than the Sun's. Its temperature of 5080 K is cooler than the Sun's. The planet EPIC 212499991 b is classified as a Super-Earth, a size class reaching 2.5 times Earth's radius. The planet's reported radius estimate is 1.6 Earth radii, larger than Earth's, and it orbits every 34.9 days. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness; repeated dips help establish orbital periods. EPIC 212499991 b was discovered by transit in 2019.
