HD 130322 b is an exoplanet with a minimum mass slightly more than that of Jupiter. It orbits the star in a very close orbit distance being only a quarter that of Mercury from the Sun. It is thus a so-called "hot Jupiter". The planet orbits the star every 10 days 17 hours in a very circular orbit.[1]
