With a dome 40 feet in diameter and 27 feet high and a capacity to seat 100, the Planetarium is one of the largest space science facilities in the California Community College System and contains some of the most modern and sophisticated equipment, including the Spitz-Goto model SG12 prime sky projector. The function of the Planetarium is threefold. It is an instructional facility for students at SRJC; it provides a variety of programs designed to support the studies of students in elementary, junior high, and high school; and it serves as a theater for public planetarium presentations on the weekends.
