K2-207: A Distant Star With a Single Known Planet
K2-207 is a star located 1180 light-years away, and one planet orbits it. The host star has a reported mass of 0.942 solar masses and a radius of 0.928 solar radii. Its reported temperature is 5520 K. Its mass estimate is smaller than the Sun's, and its temperature is cooler than the Sun's.
The planet K2-207 b is a Neptune-like world, a size class that extends to 4 times Earth's radius. It 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. K2-207 b orbits once every 12.5 days. Its radius is 2.61 Earth radii, larger than Earth's.
