Out beyond Neptune, the icy collection of distant, frozen worlds known as the Kuiper belt orbits slowly around the Sun, with each body taking hundreds or even thousands of years to complete a revolution. Most of them are incredibly small and faint, and the more than 60 years that elapsed between the discovery of Pluto and the second Kuiper belt object — 1992 QB1 — illustrates exactly that. Now, a dedicated survey, the Outer Solar System Origins Survey (OSSOS), is committed to cataloguing as many of the brightest, largest Kuiper belt objects present in our Solar System as possible. In its first big find, the collaboration just announced the discovery of a new, giant world 700 kilometers in diameter: 2015 RR245.
