EPIC 220492298 b: A Sub-Earth in a Close Orbit

EPIC 220492298 is a star located 2040 light-years away with one known planet. The host star has a measured mass of 0.95 solar masses, a radius of 1.11 solar radii, and a temperature of 5440 K. Its reported mass estimate is smaller than the Sun's, its radius estimate is larger, and its temperature is cooler.

The system's only cataloged planet is EPIC 220492298 b. It was discovered by transit in 2021, meaning it was detected as it passed in front of its star from our viewpoint. The planet is classified as a Sub-Earth, a size class for planets with radii smaller than Earth's. Its radius measures 0.99 Earth radii. It completes one orbit around its host in 0.762 days.
