<p>The Outer Solar System Origins Survey (OSSOS) is an <a href="/facts/Astronomical_survey/6BE1V8V6">astronomical survey</a> and observing program aimed at <a href="/facts/Discoverers_of_minor_planets/R4tIAzYJ">discovering</a> and tracking <a href="/facts/Trans-Neptunian_object/oF5vsbz9">trans-Neptunian objects</a> located in the outermost regions of the <a href="/facts/Solar_System/QIcLSazQ">Solar System</a> beyond the orbit of <a href="/facts/Neptune/1eucwHIC">Neptune</a>. OSSOS is designed in way that observational biases can be characterized, allowing the numbers and orbits of detected objects to be compared using a survey simulator to the populations predicted in dynamical simulations of the emplacement of trans-Neptunian objects. Conducted at the <a href="/facts/Canada-France-Hawaii_telescope/huj8fgn2">Canada-France-Hawaii telescope</a> at <a href="/facts/Mauna_Kea_Observatories/UTo3GMuv">Mauna Kea Observatories</a> (<a href="/facts/List_of_observatory_codes/7NEgYFwD">568</a>) in Hawaii, the survey has discovered 39 numbered objects as of 2018, with potentially hundreds more to follow. The survey's first numbered discovery was the object <a href="/facts/(496315)_2013_GP136/BAzfw6WD">(496315) 2013 GP136</a> in 2013.
