K2-119 and Its Neptune-Like Planet
K2-119 is a star 1190 light-years from Earth. It has a mass of 0.76 solar masses, a radius of 0.71 solar radii, and a temperature of 4740 K. Its reported mass estimate is smaller than the Sun's, its reported radius estimate is smaller than the Sun's, and its reported temperature is cooler than the Sun's. One planet orbits this host.
That planet is K2-119 b, a Neptune-like world discovered by transit in 2017. 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. K2-119 b orbits every 7.73 days and has a radius of 2.53 Earth radii, larger than Earth's.
