The Santa Rosa Junior College Planetarium is NOT offering presentations to the public for a number of important reasons. We share the vision of one day re-engaging with you in the wonder of the universe

With a dome 40 feet in diameter and 27 feet high and a capacity to seat 90, the Planetarium is one of the largest space science facilities in the California Community College System. As a Department in the Science, Technology, Engineering, & Math cluster, it is an important addition to the SRJC's Santa Rosa campus.

The Planetarium machinery includes a Goto model GX-10 star projector - the last operational one on the West Coast. This machine can reproduce the appearance of the sky onto the dome, showing the Sun, Moon, planets, and stars in their proper positions. Moreover, this projector can show the heavenly bodies as they appear from any place on Earth at any time in the past or future, for thousands of years. It can speed up the motions of the heavens so that days, years, centuries, or even  millennia can be made to pass in minutes
