HD 166724 and Its Lone Known Planet
HD 166724 is a K-type star 147 light-years away, with a spectral type of K0 IV-V. It has an age of 4 billion years, a mass of 0.81 solar masses, and a temperature of 5130 K. Its mass is smaller than the Sun's, and its temperature is cooler than the Sun's. One planet is known to orbit it.
HD 166724 b was discovered in 2012 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 1120 Earth masses and an orbital period of 5140 days. Its minimum mass is larger than Earth's and roughly 3.53 times Jupiter's mass.
