EPIC 211822797 b: A Super-Earth Orbiting a Cool Red Dwarf

EPIC 211822797 is an M0 spectral type star located 607 light-years away. As an M-type dwarf, it is a small, cool red dwarf. Its reported mass estimate is 0.61 solar masses, smaller than the Sun's, and its reported radius estimate is 0.59 solar radii, also smaller than the Sun's. The star's reported temperature is 3880 K, cooler than the Sun's, and its age is 0.79 billion years. One planet orbits this host.

That planet is EPIC 211822797 b, a Super-Earth discovered by transit in 2016. Its reported radius estimate is 1.92 Earth radii, larger than Earth's, and its orbital period is 21.2 days.
