Scientists using the Subaru Telescope announced the discovery of a new small object in the outer Solar System. Its orbit is larger and slower than any previously known minor body, taking 36,000 years to complete one orbit around the Sun. This discovery literally broadens our knowledge of the Solar System.

“This is an excellent result which made the best use of the wide and deep imaging capability of the Subaru Telescope. We hope that the discovery of similar objects will lead to a better understanding of the outer region of the Solar System,” commented Prof. Jun-ichi Watanabe, Vice Director of NAOJ and an expert on the minor bodies in the Solar System.
