K2-176 b: A Close-In Earth-Sized World
K2-176 is a star located 807 light-years away, with a mass of 0.932 solar masses, a radius of 1.01 solar radii, and a temperature of 5380 K. Its reported temperature is cooler than the Sun's. One planet orbits this host: K2-176 b.
K2-176 b was discovered in 2018 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. The planet completes one orbit every 5.33 days. Its radius is 1.49 Earth radii, which is larger than Earth's. That radius places it within the Earth-like size class, which spans planets up to 1.5 times Earth's radius.
