HD 94890 and Its Two Known Planets

HD 94890 is a K0 III star located 201 light-years away. Its reported mass is 1.74 solar masses, its reported radius is 10.7 solar radii, and its reported temperature is 4870 K. The star’s mass and radius are larger than the Sun’s, while its temperature is cooler. Two planets are known to orbit this host.

HD 94890 b was discovered in 2025 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. The planet has a minimum mass of 677 Earth masses, larger than Earth’s and roughly 2.13 times Jupiter’s mass. Its orbital period is 825 days, the shortest year among the listed planets.

HD 94890 c was also discovered in 2025 by radial velocity. It has a minimum mass of 2830 Earth masses, larger than Earth’s and roughly 8.91 times Jupiter’s mass. Its orbital period is 2490 days, the longest year among the listed planets. Among the listed planets, HD 94890 b has the smallest minimum mass and HD 94890 c has the largest minimum mass.
