GJ 832 is a star 16.2 light-years away with a single known planet. Its spectral type is M1.5, making it a small, cool red dwarf. The star's reported mass estimate is 0.45 solar masses, smaller than the Sun's, and its reported radius estimate is 0.48 solar radii, also smaller than the Sun's. Its reported temperature of 3660 K is cooler than the Sun's.
The planet GJ 832 b was discovered in 2008 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion, with repeated wobbles revealing the planet and its orbital period. GJ 832 b has a mass of 315 Earth masses, larger than Earth's, and an orbital period of 3850 days.
