HD 222582 and Its Planet
HD 222582 is a Sun-like G-type dwarf 138 light-years away. It is 6 billion years old, has 1 solar mass, a radius of 1.06 solar radii, and a temperature of 5780 K. One planet orbits this host.
That planet, HD 222582 b, was found in 1999 by the radial velocity method, which detects the wobble a planet's gravity induces in its star. It has a minimum mass of 2660 Earth masses, meaning its true mass is at least that large, and its minimum mass is roughly 8.37 times Jupiter's mass. It completes an orbit every 572 days.
