K2-337 b: A Neptune-Like Planet Orbiting a Star
K2-337 is a star 1380 light-years away with 0.94 solar masses, 1.32 solar radii, and a temperature of 5870 K. Its mass estimate is smaller than the Sun's, while its radius estimate is larger and its temperature is hotter than the Sun's.
One planet orbits this host. That planet, K2-337 b, is Neptune-like, a size class that reaches 4 times Earth's radius. Its radius estimate is 2.62 Earth radii, larger than Earth's. It was 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. Repeated dips help establish orbital periods. K2-337 b completes one orbit every 16.3 days.
