HD 170469 and Its Planet
HD 170469 is a star 196 light-years away with a spectral type of G5 IV. It is 6.7 billion years old and has a mass of 1.14 solar masses, a radius of 1.22 solar radii, and a temperature of 5810 K. Its reported mass and radius estimates are both larger than the Sun's. One planet orbits this host.
That planet is HD 170469 b, discovered in 2007 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. Its minimum mass is 210 Earth masses, a lower bound on its true mass that is larger than Earth's. It completes one orbit every 1150 days.
