HD 82886 and Its Lone Known Planet

HD 82886 is a G0 star located 414 light-years away, with a mass of 1.06 solar masses and an age of 7 billion years. It is cooler than the Sun, at 5110 K, and its reported radius of 4.8 solar radii is larger than the Sun's. One planet is known to orbit this star.

That planet, HD 82886 b, was discovered in 2011 using the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. It has a minimum mass of 741 Earth masses - a lower bound on its true mass, and roughly 2.33 times Jupiter's mass - and it completes one orbit every 705 days.
