HD 191806 and Its Planet

HD 191806 is a K0 star 214 light-years away, with one known planet in orbit. The star is 2.9 billion years old, holds 1.14 solar masses, and has a temperature of 6010 K. Its reported mass estimate is larger than the Sun's, and its reported temperature is hotter than the Sun's.

The planet is HD 191806 b, discovered in 2016 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. HD 191806 b has a mass of 2970 Earth masses - roughly 9.33 times Jupiter's mass, and larger than Earth's - and an orbital period of 1600 days.
