K2-320 b: A Neptune-Like World Orbiting a Cool Dwarf
K2-320 is a star 355 light-years away, and it hosts exactly one known planet. The star has a mass of 0.248 solar masses and a radius of 0.274 solar radii, making it smaller than the Sun in both respects. Its temperature is 3240 K, cooler than the Sun's.
The planet, K2-320 b, is a Neptune-like world discovered in 2020 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. Repeated dips help establish orbital periods. K2-320 b completes an orbit every 2 days, and its radius is 2.62 Earth radii, larger than Earth's.
