11 Com: A Distant Star With a Massive Minimum-Mass Planet
The host star 11 Com lies 304 light-years away and belongs to a two-star system. It is a G8 III star with a mass of 2.7 solar masses, a radius of 19 solar radii, and a temperature of 4740 K. Its reported mass and radius estimates are larger than the Sun's, while its reported temperature is cooler than the Sun's. One planet orbits this host: 11 Com b.
11 Com b was discovered in 2007 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion; repeated wobbles reveal the planet and its orbital period. The planet's orbital period is 323 days. Its minimum mass is 4910 Earth masses, which is larger than Earth's and roughly 15.5 times Jupiter's mass.
