Gl 49 b: A Close-Ranging Planet Around a Cool Dwarf
Gl 49 is an M1.5 V star, a small, cool red dwarf, located 32.1 light-years away. It has a reported mass of 0.515 solar masses and a radius of 0.511 solar radii, both smaller than the Sun's. Its temperature is 3810 K, cooler than the Sun's. One planet is known to orbit this host.
That planet is Gl 49 b, discovered in 2019 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. Gl 49 b has a minimum mass of 5.63 Earth masses, larger than Earth's, and an orbital period of 13.9 days. Its minimum mass is a lower bound on its true mass.
