K2-288 B and Its Super-Earth

K2-288 B is an M3 V star, an M-type main-sequence dwarf, located 214 light-years away. Its reported mass estimate is 0.33 solar masses and its reported radius estimate is 0.32 solar radii. The star's reported temperature is 3340 K, and its age carries a reported lower limit of 1 billion years. One planet orbits this host.

That planet is K2-288 B b, a Super-Earth discovered by transit in 2018. Its reported radius estimate is 1.9 Earth radii, larger than Earth's, which places it within the Super-Earth size class. It completes one orbit every 31.4 days.
