K2-323: A Cool Star with a Super-Earth
K2-323 is a star located 386 light-years from Earth, and it hosts one known planet. The star has a reported mass estimate of 0.533 solar masses and a radius estimate of 0.537 solar radii, both smaller than the Sun's. Its temperature is 3650 K, cooler than the Sun's.
The planet, K2-323 b, was 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. K2-323 b completes an orbit every 24.9 days. It is classified as a Super-Earth, a size class that compares radius with Earth's and reaches 2.5 times Earth's radius. Its radius is 2.1 Earth radii, larger than Earth's.
