K2-351 b: A Neptune-like World in a Distant Star System
K2-351 is a star located 2,270 light-years away. It has a mass of 1.02 solar masses, a radius of 1.05 solar radii, and a temperature of 5770 K. One planet orbits this host.
That planet is K2-351 b, a Neptune-like world discovered in 2021 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. It completes an orbit every 7.81 days and has a radius of 2.54 Earth radii, larger than Earth's.
