HD 164595 and Its Planet
HD 164595 is a G2V star located 92.2 light-years away, with one known planet in orbit. The star has an age of 7.12 billion years, a mass of 0.97 solar masses, a radius of 1.04 solar radii, and a temperature of 5750 K. Its reported mass estimate is smaller than the Sun's, while its reported radius estimate is larger than the Sun's; its reported temperature is cooler than the Sun's.
The sole listed planet is HD 164595 b, discovered in 2015 by the radial velocity method. This technique measures the wobble a planet's gravity induces in its star's motion, and repeated wobbles reveal the planet and its orbital period. HD 164595 b has a minimum mass of 16.1 Earth masses, a lower bound on its true mass, which is larger than Earth's. It completes one orbit in 40 days.
