Planetarium Programs – Waukesha

The Horwitz DeRemer Planetarium at Retzer Nature Center brings the cosmos to life through engaging shows designed for families. Each presentation uses cutting-edge projection technology to take viewers on immersive journeys—you might fly through Saturn's rings, land on Mars, or travel to distant galaxies without ever leaving your seat. Shows run regularly throughout the fall and winter, with different programs suited to various age groups and interests, from space adventures perfect for young children to more complex astronomy topics for older kids. Tickets cost just $5 per person, and you can purchase them up to showtime if seats are available. The planetarium also welcomes group reservations for scouts, birthday parties, and community organizations. The theater and lobby area are fully wheelchair accessible, making it easy for all families to enjoy. For details about specific showtimes, show topics, or to book a private group experience, call 262-970-4139 or visit their online ticketing system. Between shows, families can explore the surrounding Retzer Nature Center grounds.
