K2-393 b: A Super-Earth in a Distant System
K2-393 is a star located 867 light-years away. It has a mass of 0.881 solar masses, a radius of 1.07 solar radii, and a temperature of 5680 K. Its reported radius estimate is larger than the Sun's. One planet orbits this host.
That planet is K2-393 b, a Super-Earth discovered by transit in 2022. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. K2-393 b has a radius of 2.35 Earth radii, and its reported radius estimate is larger than Earth's. Its orbital period is 10.4 days.
