K2-394 and Its Super-Earth

K2-394 is a star 320 light-years away with one known planet. The host star has a mass of 0.478 solar masses and a radius of 0.631 solar radii, both smaller than the Sun's. Its temperature is 4940 K, cooler than the Sun's.

The planet K2-394 b is 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. Its orbital period is 5.1 days, and its radius is 1.69 Earth radii, larger than Earth's.
