ORION is an amateur science and astronomy club centered in Oak Ridge, TN that was founded in April 1974 by a group of scientists at the United States Department of Energy facility in Oak Ridge, Tennessee. Our purpose is to promote learning and inquiry throughout the cities of Oak Ridge and Knoxville, and the counties of Anderson, Knox, and Roane. Topics covered include physics, solar system astronomy, and interstellar. You don’t have to be a scientist to join us! Most activities are open to the public.
