EPIC 201497682 b: A Close-Orbiting Sub-Earth
EPIC 201497682 is a star 825 light-years away with one known planet. The star has a mass of 0.74 solar masses, a radius of 0.686 solar radii, and a temperature of 4670 K, making it less massive, smaller, and cooler than the Sun.
The planet EPIC 201497682 b was discovered by transit in 2019. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. This planet completes an orbit every 2.13 days. Its radius of 0.692 Earth radii makes it a Sub-Earth, a size class for planets smaller than Earth, and its radius is smaller than Earth's.
