Spaceship Earth is a dark ride attraction at the Epcot theme park at the Walt Disney World in Bay Lake, Florida. The geodesic sphere in which the attraction is housed has served as the symbolic structure of Epcot since the park opened in 1982.

The geometric name for the iconic EPCOT "ball," known officially as Spaceship Earth, is a geodesic sphere. Specifically, its structure is derived from a Class 2 geodesic polyhedron with a frequency of division equal to 8. This means the surface is composed of 11,520 smaller isosceles triangles that are arranged into 3,840 "points" (panels) to create its distinctive faceted, golf-ball-like appearance. Unlike a simple geodesic dome, which is only a partial sphere, Spaceship Earth is a complete sphere supported by six massive legs that extend deep into the ground. Designed in the late 1970s with input from the legendary Buckminster Fuller (the "father" of geodesic structures), the sphere stands 180 feet tall and is 165 feet in diameter. The Alucobond skin panels are designed to funnel rainwater through 1/16-inch gaps into a hidden drainage system that eventually feeds into the World Showcase lagoon, preventing water from dripping onto guests below. In 2026, it remains a marvel of structural engineering, perfectly balancing mathematical precision with the aesthetic of a "futuristic" landmark.
