K2-356 and Its Super-Earth
K2-356 is a star 1160 light-years away. It has 0.96 solar masses and a radius of 0.832 solar radii, smaller than the Sun's. Its temperature of 5500 K is cooler than the Sun's. One planet orbits this host.
That planet, K2-356 b, is a Super-Earth discovered by transit in 2021. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. K2-356 b orbits every 21 days and has a radius of 2.29 Earth radii, larger than Earth's.
