Outer Solar System Origins Survey

(survey searching for trans-Neptune objects)

The Outer Solar System Origins Survey (OSSOS) is a Survey searching for Trans-Neptunian Objects (TNOs), i.e., Minor Planets orbiting beyond Neptune. It is performed with the Canada-France-Hawaii Telescope MegaPrime 1-square-degree imager, regularly observing 21-square-degree regions over 16-month periods. It was begun in 2013 and in 2017, 8 such regions had been surveyed, with over 800 objects were discovered. Observation was designed to allow extrapolation of overall population statistics.
