HD 219139 and Its Planet

HD 219139 is a star 342 light-years away. Its spectral type is G5 III, and it is cooler than the Sun, with a temperature of 4830 K. The star has a mass of 1.46 solar masses and a radius of 11.2 solar radii, both larger than the Sun's corresponding values.

One planet orbits this star: HD 219139 b, discovered in 2021 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 248 Earth masses, meaning its true mass is at least this large. Its orbital period is 276 days, so it completes one orbit in that time.

HD 219139 b's minimum mass is larger than Earth's.
