Gliese 48 b: A Close Red Dwarf Planet
Gliese 48 is an M3.5 V star, a small, cool red dwarf, located 26.9 light-years away. It has one known planet.
The host star's reported mass estimate is 0.47 solar masses, its reported radius estimate is 0.463 solar radii, and its temperature is 3450 K - all smaller or cooler than the Sun's corresponding values.
The single planet, Gliese 48 b, was discovered in 2026 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. Its minimum mass is 8.11 Earth masses, larger than Earth's, and its orbital period is 39.6 days.
