APS HEfferan Planetarium

Hefferan Planetarium at ECA/CEC was built in 1975. All second through fifth grade APS elementary teachers may schedule their classes for a grade-level appropriate planetarium show/demonstration that promotes life-long learning in astronomy. The planetarium seats up to 66 students/adults per show. Each show lasts about an hour. Approximately 10,000 APS elementary students see a show at Hefferan Planetarium every year.
