K2-150 b: A Super-Earth in a Distant Star System
K2-150 is an M2.5 V star located 334 light-years away. This small, cool red dwarf has a mass of 0.457 solar masses, a radius of 0.436 solar radii, and a temperature of 3500 K, making it less massive, smaller, and cooler than the Sun. One planet orbits it.
That planet is K2-150 b, a Super-Earth discovered by the transit method in 2018. Its radius is 2 Earth radii, larger than Earth's, and its orbital period is 10.6 days.
