HD 109246 and Its Planet

HD 109246 is a star 221 light-years away with a spectral type of G0 V, a Sun-like classification. It has a mass of 1.01 solar masses, a radius of 1.02 solar radii, and a temperature of 5840 K, which is hotter than the Sun's. One planet orbits this star.

HD 109246 b was discovered in 2010 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. The planet has a minimum mass of 273 Earth masses, a lower bound on its true mass that is larger than Earth's, and an orbital period of 68.3 days.
