HD 85390 and Its Planet
HD 85390 is a K0 star 109 light-years away. Its reported mass is 0.76 solar masses, smaller than the Sun's, and its reported temperature of 5190 K is cooler than the Sun's. The star is 7.2 billion years old. One planet orbits this host.
That planet, HD 85390 b, was discovered in 2011 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. Its minimum mass is 31.5 Earth masses, larger than Earth's, and its orbital period is 800 days.
