HD 63765 and Its Lone Known Planet

HD 63765 is a G9 V star 106 light-years away. Its spectral class of G9 V is a G-type dwarf. The star is 4.77 billion years old and holds 0.865 solar masses, a mass estimate smaller than the Sun's, with a temperature of 5430 K, cooler than the Sun's.

One planet orbits this host. HD 63765 b was found in 2011 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. The planet's minimum mass is 168 Earth masses, larger than Earth's, and it completes one orbit every 358 days. A minimum mass is a lower bound on the planet's true mass.
