GJ 2030 and Its Two Known Planets

GJ 2030 is a single star located 121 light-years away. Two planets are known to orbit it. The host star has a mass of 0.96 solar masses, a radius of 2.24 solar radii, and a temperature of 5490 K. Its radius is larger than the Sun's, and its temperature is cooler than the Sun's.

Both planets were discovered in 2022 using the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. GJ 2030 b has a minimum mass of 4.77 Earth masses, larger than Earth's, and an orbital period of 2.38 days. GJ 2030 c has a mass of 4070 Earth masses, roughly 12.8 times Jupiter's mass, and an orbital period of 25500 days. Among the listed planets, GJ 2030 b has the shortest year and GJ 2030 c the longest.
