HIP 86221 b: A Planet Around a K-Type Dwarf
HIP 86221 is a K5 V star, a main-sequence dwarf somewhat cooler than the Sun, located 96.2 light-years away. Its reported mass estimate is 0.79 solar masses, smaller than the Sun's. One planet orbits this star.
That planet, HIP 86221 b, was discovered in 2021 using 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. HIP 86221 b has a minimum mass of 226 Earth masses, larger than Earth's, meaning its true mass is at least this value. It completes one orbit in 2.22 days.
