HD 129445 and Its Lone Known Planet

HD 129445 is a G6 V star 220 light-years away, a Sun-like dwarf with a reported mass of 1 solar masses, a radius of 1.16 solar radii, and a temperature of 5640 K. Its radius estimate is larger than the Sun's. One planet has been found orbiting this star.

That planet, HD 129445 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 509 Earth masses, larger than Earth's and roughly 1.6 times Jupiter's mass. A minimum mass is a lower bound on a planet's true mass. HD 129445 b completes one orbit in 1840 days.
