HD 164509 and Its Planet
HD 164509 is a G-type dwarf, or G5 V star, located 173 light-years away. The star is estimated to be 1.1 billion years old, with a mass of 1.13 solar masses, a radius of 1.06 solar radii, and a temperature of 5920 K. Each of those values is larger or hotter than the Sun's corresponding value. One planet orbits this host.
HD 164509 b was discovered in 2012 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. The planet's minimum mass is 141 Earth masses, larger than Earth's, and its orbital period is 280 days.
