GJ 4274: A Nearby Red Dwarf with Two Known Planets

GJ 4274 is an M4.5 V star, a small, cool red dwarf, located 23.6 light-years away. Its reported mass is 0.18 solar masses and its radius is 0.19 solar radii, both smaller than the Sun's, and its temperature of 3230 K is cooler than the Sun's. The star's age is given as 0.12 billion years. Two planets are known to orbit it.

GJ 4274 b was discovered in 2026 by the radial velocity method and has a minimum mass of 2.97 Earth masses, larger than Earth's, and an orbital period of 1.63 days, the shortest year among the listed planets. GJ 4274 c was also discovered in 2026 by radial velocity and has a minimum mass of 8.39 Earth masses, larger than Earth's, with an orbital period of 69.6 days, the longest year among the listed planets. Among the listed planets, GJ 4274 b has the smallest minimum mass and GJ 4274 c the largest.
