HD 7449 and Its Planet
HD 7449 is a star system 126 light-years away with two cataloged stars. Its host star is an F9.5 V star, a main-sequence dwarf hotter and more massive than the Sun. The star's reported mass estimate is 1.05 solar masses, its reported radius estimate is 1.01 solar radii, and its reported temperature is 6020 K. It is 2.1 billion years old. One planet orbits this host.
That planet, HD 7449 b, was discovered in 2011 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. It has a mass of 2600 Earth masses, roughly 8.17 times Jupiter's mass, and an orbital period of 1270 days. Its mass estimate is larger than Earth's.
