Welcome to the OSU Planetarium!

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.

Campus Construction Update (2014 Aug 1):
Summer construction at OSU continues to impact access to the planetarium.  See our Directions page for updated information on how to get to the planetarium, and be sure to allow plenty of time to navigate across campus.
