TYC 3667-1280-1 b: A Giant Planet Around a Distant Star
TYC 3667-1280-1 is a star located 1560 light-years away. It has a mass of 1.87 solar masses and a radius of 6.26 solar radii, both larger than the Sun's corresponding values. Its temperature is 5130 K, cooler than the Sun's, and its age is 1.35 billion years. One planet orbits this host.
That planet is TYC 3667-1280-1 b, discovered in 2016 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. It has a minimum mass of 1720 Earth masses and an orbital period of 26.5 days, the time it takes to complete one orbit. Its minimum mass is larger than Earth's and roughly 5.4 times Jupiter's mass.
