HD 208487 and Its Planet
HD 208487 is a G-type dwarf star 147 light-years away, with a spectral type of G2 V that marks it as Sun-like. It is 1.95 billion years old and has a mass of 1.15 solar masses, a radius of 1.16 solar radii, and a temperature of 6130 K. Its reported mass and radius estimates are larger than the Sun's, and its reported temperature is hotter than the Sun's. One planet orbits this host.
That planet, HD 208487 b, was discovered in 2004 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. Its minimum mass is 146 Earth masses, a lower bound on its true mass and larger than Earth's. It completes one orbit every 129 days.
