Tau Boo and Its Close-Orbiting Planet

Tau Boo is a star 51.1 light-years away with a spectral type of F7V, meaning it is an F-type main-sequence dwarf. It has an age of 1.64 billion years, a mass of 1.34 solar masses, a radius of 1.46 solar radii, and a temperature of 6390 K. Its mass and radius are each larger than the Sun's, and its temperature is hotter than the Sun's. One planet is known to orbit this host.

That planet, tau Boo b, was discovered in 1996 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 1370 Earth masses, a lower bound on its true mass, and an orbital period of 3.31 days. Its minimum mass is larger than Earth's and roughly 4.32 times Jupiter's mass.
