K2-377: A Cool Dwarf Star with a Super-Earth
K2-377 is a star located 636 light-years away. It has a mass of 0.821 solar masses, a radius of 0.691 solar radii, and a temperature of 4200 K. Its reported radius estimate is smaller than the Sun's, and its reported temperature is cooler than the Sun's. One planet orbits this host.
That planet, K2-377 b, is classified as a Super-Earth, a size class that reaches 2.5 times Earth's radius. Its radius is 1.69 Earth radii, larger than Earth's. It was discovered in 2022 by the transit method, in which a planet passes in front of its star from our viewpoint and causes a small dip in observed brightness.
K2-377 b completes an orbit in 12.8 days.
