K2-366 b: A Super-Earth in a Single-Planet System
K2-366 is a star located 606 light-years away, with one planet orbiting it. The host star has a mass of 0.825 solar masses and a radius of 0.94 solar radii. Its temperature is 5600 K, cooler than the Sun's.
The system's only known planet, K2-366 b, is classified as a Super-Earth. 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. K2-366 b orbits with a period of 15.9 days, and its radius is 2.36 Earth radii, larger than Earth's.
