TYC 2187-512-1 b: A Nearby Red Dwarf and Its Planet

TYC 2187-512-1 is a star 50.5 light-years away with a spectral type of M1.0 V, making it a small, cool red dwarf. It has a mass of 0.498 solar masses and a radius of 0.495 solar radii. Its temperature is 3730 K. One planet orbits this star.

The planet is named TYC 2187-512-1 b. It was discovered in 2022 using the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. Its minimum mass is 105 Earth masses, a lower bound on its true mass. Its orbital period is 692 days, the time it takes to complete one orbit.
