HD 100508 and Its Planet

HD 100508 is a K1 IV star 107 light-years away with one known planet. Its spectral type places it in the K class, cooler than the Sun, and its measured temperature of 5420 K reflects that. The star's other measured properties are a mass of 0.94 solar masses and a radius of 1.02 solar radii.

The single planet orbiting the star, HD 100508 b, was discovered in 2026 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. Its orbital period is 5680 days, and its mass is 381 Earth masses, roughly 1.2 times Jupiter's mass.
