HIP 4845 b: A Planet Around a Cool Dwarf
HIP 4845 is an M0 V star, an M-type main-sequence dwarf, located 68.8 light-years away. It has a mass of 0.63 solar masses, a radius of 0.647 solar radii, and a temperature of 4010 K. Its mass and radius are smaller than the Sun's, and its temperature is cooler.
One planet orbits this star. HIP 4845 b was discovered in 2020 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. The planet has a minimum mass of 14.4 Earth masses, larger than Earth's, meaning its true mass is at least this value. It completes one orbit every 34.2 days.
