HD 110014 and Its Planet
HD 110014 is a K2 III star 329 light-years away, with a spectral type indicating a cooler, more evolved star than the Sun. Its age is 0.95 billion years, its mass is 2.17 solar masses, and its radius is 20.9 solar radii. The star's temperature is 4450 K. The reported mass and radius estimates are larger than the Sun's, while the reported temperature is cooler than the Sun's.
One planet is known to orbit this host. HD 110014 b was discovered in 2009 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. Its minimum mass is 3520 Earth masses, a lower bound on its true mass rather than an ordinary mass estimate. This minimum mass is larger than Earth's and is roughly 11.1 times Jupiter's mass. The planet completes an orbit in 835 days.
