The new planet is believed to be part of the Kuiper Belt, a large ring of icy objects that orbit beyond Neptune and are believed to be remnants of the material that formed the solar system. Objects in the Kuiper Belt are believed to have had a close encounter with Neptune, which then scattered them with its gravitational force into eccentric orbits. Pluto is also in the Kuiper Belt.
