HD 149806 and Its Planet
HD 149806 is a K0V star 66.1 light-years away, with one planet. Its spectral type places it in the K-class dwarf range. The star is 8.36 billion years old and has a mass of 0.91 solar masses, a radius of 0.89 solar radii, and a temperature of 5360 K. Its reported mass and radius estimates are smaller than the Sun's, and its reported temperature is cooler than the Sun's.
The planet HD 149806 b was discovered in 2022 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. The planet has a mass of 4000 Earth masses and an orbital period of 16500 days. Its reported mass estimate is larger than Earth's and roughly 12.6 times Jupiter's mass.
