HD 93083 and Its Two Planets
HD 93083 is a K-type star 93 light-years away with a spectral type of K2 IV-V. It has a mass of 0.836 solar masses, a radius of 0.837 solar radii, a temperature of 5030 K, and an age of 10.7 billion years. The star's reported mass and radius estimates are smaller than the Sun's, and its reported temperature is cooler than the Sun's. Two planets are known to orbit it.
HD 93083 b was discovered in 2005 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion; repeated wobbles reveal the planet and its orbital period. It has a minimum mass of 143 Earth masses and an orbital period of 145 days.
GJ 1137 c was discovered in 2026, also by radial velocity. It has a minimum mass of 5.12 Earth masses and an orbital period of 9.64 days. A minimum mass is a lower bound on a planet's true mass. Both planets' minimum masses are larger than Earth's, and among the listed planets, GJ 1137 c has the shortest year while HD 93083 b has the longest. GJ 1137 c also has the smallest minimum mass, and HD 93083 b has the largest.
