The George H. Clever Planetarium at San Joaquin Delta College provides a comprehensive series of space science and earth science education programs to school children from Stockton, Manteca, Lodi, Tracy, Rio Vista, Sacramento, Modesto and the Mother Lode, including Sonora. The planetarium regularly hosts school field trips from as far away as Fresno in the south to Chico in the north.

The Clever Planetarium features a Spitz 512 prime sky instrument nicknamed Herman, which projects the stars on a 33 foot aluminum dome. This instrument can show the sky of any datexpast, present or futurex from any location on Earth. All the motions of the planet Earth can be simulated and accelerated so that days, years, centuries or a millennia can be made to pass before the viewers’ eyes in a matter of minutes.

The Stockton Astronomical Society meets at the Clever Planetarium on the second Thursday of each month, at 7:30 pm. Meetings are open to the public. The purpose of the Society is to foster interest in and promote the general knowledge of astronomy and related sciences. Whether your level of interest in the night sky is casual or serious, you will find many other members with similar interests. Although the membership includes many serious amateur astronomers, and a couple of professionals, most members do not own telescopes but enjoy membership simply to satisfy a general curiosity about the night sky and about the cycles of our solar system which affect our daily lives.
