This gallery includes four different exhibits; Our Solar System, Living and Working in Space, Mars and the Moon, and Visions of Space Exploration. Our Solar System This permanent exhibit focuses on the planets within the Solar System and showcases planetary models in an array of sizes. Saturn, Jupiter, Uranus, and Neptune hang high above the second-floor, nearly 30 feet high. These four models are the largest in the country to be displayed inside a museum or science center. Jupiter, the largest of the models, weighs more than 750 pounds, has a diameter of 10 feet, and hangs approximately 22 feet in the air. Saturn is eight-and-a-half feet in diameter and weighs 450 pounds, with an additional 495 pounds of rings encircling the planet's body. Hanging more than 30 feet high, Saturn floats above Uranus and Neptune, which each weigh around 65 pounds. The models are composed of heavy-duty Styrofoam which is painted to resemble each of the planets. The Solar System is completed with smaller models of Earth, Mars, Venus, and Mercury mounted at the visitor's level. Created to be a scale model system, Earth is about the size as a soccer ball and Mercury the size of a baseball.
