GJ 3090 and Its Two Known Planets
GJ 3090 is an M2 V star, a small, cool red dwarf, located 73.3 light-years away. Its reported mass estimate is 0.519 solar masses and its reported radius estimate is 0.516 solar radii, both smaller than the Sun's. Its reported temperature is 3560 K, cooler than the Sun's. Two planets are known to orbit this star.
GJ 3090 b is a Super-Earth discovered by the transit method in 2022. It has a reported mass estimate of 4.52 Earth masses and a reported radius estimate of 2.18 Earth radii. Its mean density is 2.4 g/cm³, 0.436 times Earth's. It completes an orbit in 2.85 days, the shortest year among the listed planets. Both its reported mass and radius estimates are larger than Earth's.
GJ 3090 c was discovered by the radial velocity method in 2026. Its minimum mass is 10 Earth masses, larger than Earth's. It orbits in 15.9 days, the longest year among the listed planets.
