HD 238090 and Its Planet
HD 238090 is an M0.0 V star, a small, cool red dwarf, located 49.7 light-years from Earth. It has a mass of 0.578 solar masses and a radius of 0.57 solar radii, both smaller than the Sun's. Its temperature is 3930 K, cooler than the Sun's. One planet is known to orbit this star.
HD 238090 b was discovered in 2020 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. The planet has a minimum mass of 6.89 Earth masses, meaning its true mass is at least this much, and it is larger than Earth. Its orbital period is 13.7 days.
