HD 165155 and Its Lone Known Planet

HD 165155 is a G8 V star 207 light-years away, a Sun-like dwarf somewhat cooler than the Sun at 5430 K. The star is 11 billion years old, holds 1.02 solar masses, and spans 0.95 solar radii. One planet has been found around this host.

That planet is HD 165155 b, discovered in 2016 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. Its minimum mass is 919 Earth masses, a lower bound on its true mass and roughly 2.89 times Jupiter's mass, and it completes an orbit every 435 days.
