Outer Solar System Origins Survey

(OSSOS)
(2013-2017 survey that searched for trans-Neptune objects)

The Outer Solar System Origins Survey (OSSOS) was a survey searching for trans-Neptune objects (TNOs), i.e., minor planets orbiting beyond Neptune. It was performed with the Canada-France-Hawaii Telescope MegaPrime 1-square-degree imager, regularly observing 21-square-degree regions over 16-month periods. Observations were from 2013 to 2017, with over 800 solar system object discovered. Observation was designed to allow extrapolation of overall population statistics.

Col-OSSOS (for Colours of the Outer Solar System Origins Survey) is a follow-up photometric survey of the objects also using Gemini North.
