HD 144899 and Its Planet
HD 144899 is a star 377 light-years away with one known planet. The star's reported mass estimate is 1.16 solar masses, larger than the Sun's, and its radius of 1.65 solar radii is also larger than the Sun's. Its temperature of 6130 K is hotter than the Sun's.
The planet HD 144899 b was discovered in 2022 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 20.3 Earth masses, a lower bound on its true mass, and this is larger than Earth's minimum mass. It orbits HD 144899 every 40.4 days, the time it takes to complete one orbit.
