HD 206255 and Its Lone Known Planet
HD 206255 is a G-type star 245 light-years away with a spectral type of G5 IV/V. It has a mass of 1 solar masses, a radius of 2.21 solar radii, and a temperature of 5640 K; its radius estimate is larger than the Sun's. One planet is known to orbit this star.
That planet, HD 206255 b, was discovered in 2019 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. HD 206255 b has a minimum mass of 34.2 Earth masses, a lower bound on its true mass, and its minimum mass is larger than Earth's. It completes one orbit every 96 days.
