HD 219077 and Its Planet

HD 219077 is a G8 V star 95.2 light-years away. The "G8 V" label identifies a Sun-like, main-sequence dwarf, and the star is 8.9 billion years old. Its mass is 1.05 solar masses, its radius is 1.91 solar radii, and its temperature is 5360 K. One planet is known to orbit this star.

That planet, HD 219077 b, was discovered in 2012 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. HD 219077 b has a mass of 3060 Earth masses and an orbital period of 5480 days. Its mass is larger than Earth's and roughly 9.62 times Jupiter's mass.
