HIP 19976 b: A Close-Orbiting Planet Around a Cool Dwarf

HIP 19976 is a star 131 light-years away with a mass of 0.67 solar masses, a radius of 0.772 solar radii, and a temperature of 4320 K. Its reported mass and radius estimates are smaller than the Sun's, and its reported temperature is cooler than the Sun's. One planet has been found orbiting this star.

That planet, HIP 19976 b, was discovered in 2022 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. HIP 19976 b has a minimum mass of 21.6 Earth masses, larger than Earth's, and an orbital period of 50.7 days.
