Pauling

Mass Effect 2 & Mass Effect 3
A hydrogen-methane gas giant, Pauling's gravitational field is believed to have cleared most of what would otherwise have been a sizeable asteroid belt. The 2163 mission of the space probe "Ultimate" gave the inhabitants of Watson reams of data reinforcing this theory, giving the colonists an accurate count of its moons (66), rings, moonlike ring objects, and more than 200 impact craters on the surface of its metallic core. "Ultimate" has since been retrieved for re-use on subsequent missions within the solar system.
