The OSU Planetarium, located in Smith Laboratory on the Ohio State University main campus in Columbus, serves the University and central-Ohio communities with educational programs in Astronomy.  Operated since 1968 by the Department of Astronomy, the Planetarium is a 63-seat 30-foot dome theater with a state-of-the-art Spitz SciDome XD digital projection system that gives exquisite views of the night sky from Columbus, and lets us take you on digital journeys to the planets, stars, and distant galaxies.

After a 16-month renovation, the OSU Planetarium is now open! We are now accepting requests for private group shows. Please visit our public shows page for information to see the schedule for and reserve seats for one of our regular public programs.
