GJ 3341 and Its Planet

GJ 3341 is a small, cool red dwarf of spectral type M2.5, located 77 light-years away. Its reported mass is 0.47 solar masses, its reported radius is 0.439 solar radii, and its temperature is 3530 K. Each of these estimates is smaller or cooler than the corresponding value for the Sun. One planet orbits this star.

That planet, GJ 3341 b, was discovered in 2015 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion; repeated wobbles reveal the planet and its orbital period. GJ 3341 b has a minimum mass of 6.6 Earth masses, larger than Earth's, and an orbital period of 14.2 days.
