HD 130322 and Its Planet
HD 130322 is a G5 star located 104 light-years away. Its spectral type places it in the same broad temperature class as the Sun, though the star's reported temperature of 5370 K is cooler than the Sun's. The star's reported radius of 0.84 solar radii is smaller than the Sun's. It has a mass of 0.9 solar masses and an age of 1 billion years.
One planet orbits this host. HD 130322 b was discovered in 1999 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 completes one orbit in 10.7 days. Its minimum mass, a lower bound on its true mass, is 365 Earth masses, larger than Earth's and roughly 1.15 times Jupiter's mass.
