The Arne Slettebak Planetarium

The Arne Slettebak Planetarium is a 63-seat 30-foot dome theater located on the 5th floor of Smith Laboratory on the OSU main campus in Columbus, Ohio.  We have been offering educational programs on the night sky to OSU students and the central Ohio community since 1968.


We offer regular public programming as well as by-request programming for groups. Please see our website for details on available programs and shows.


We were closed for renovations beginning in June 2012, but re-opened to the public on October 12, 2013!


We are now celebrating 2 years of being back open with a number of events this October.

Sorry, there are no upcoming events
