Gl 378 b: A Close-In Planet Around a Cool Red Dwarf

Gl 378 is an M1 red dwarf located 48.8 light-years away. The star has a reported mass of 0.56 solar masses and a radius of 0.56 solar radii, both smaller than the Sun's, and a temperature of 3880 K, cooler than the Sun's. One planet orbits this host.

That planet, Gl 378 b, was discovered in 2019 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. Its minimum mass is 13 Earth masses, larger than Earth's, and its orbital period is 3.82 days.
