Potential discovery of a dozen objects beyond Pluto could reveal a new section of the solar system we never knew about
By Harry Baker published
Astronomers may have detected a dozen large objects lurking beyond the Kuiper Belt at the edge of our solar system, suggesting there could be another equally massive, "second Kuiper Belt" hiding beyond the orbit of Pluto.
