HD 16905 is a K3 V star 130 light-years away. A trailing V marks a main-sequence dwarf, and the K class is cooler and redder than the Sun's G type. The star's reported mass estimate is 0.79 solar masses, its radius estimate is 0.775 solar radii, and its temperature is 4870 K - all smaller or cooler than the Sun's corresponding values. One planet is known to orbit this host.
That planet, HD 16905 b, was discovered in 2022 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. Its mass is 3590 Earth masses, roughly 11.3 times Jupiter's mass and larger than Earth's. It completes one orbit every 10300 days.
