HD 89307 and Its Solitary Known Planet
HD 89307 is a G-type main-sequence star located 104 light-years from Earth. Its spectral type is G0 V, classifying it as a Sun-like dwarf, and it hosts one known planet. The star has an age of 6.76 billion years, a mass of 1.03 solar masses, and a radius of 1.05 solar radii, making it slightly larger than the Sun. Its temperature of 5950 K is hotter than the Sun's.
The sole known planet, HD 89307 b, was discovered in 2009 using the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. The planet has a minimum mass of 671 Earth masses - a lower bound on its true mass - which is roughly 2.11 times Jupiter's mass. It completes one orbit every 2170 days.
