Visit Eartha - the World's Largest Rotating, Revolving Globe!
Housed in a three-story glass atrium, Eartha was first revealed in July 1998 and quickly gained international attention and earned the title of "World's Largest Revolving/Rotating Globe" by the editors of the Guinness Book of World Records, and still holds that record today. Representing earth as it is seen from space, every continent is beautifully detailed, with vivid colors illustrating all levels of vegetation, major roadways and cities. Ocean depths are also completely represented.

Eartha has a circumference of nearly 130 feet and measures 41.5 feet in diameter with an internal truss structure comprised of aluminum tubing that if laid end-to-end would stretch for nearly three miles.

Eartha Factoids:
  • Two years to construct in 1997-98
  • Four months to refurbish in 2012
  • Map scale of 1:1,000,000, which means one inch on Eartha equals nearly 16 miles on Earth
  • Weighs 5,600 pounds ? nearly three tons
  • Rotates on its axis at 23.5 degrees, just as Earth does
  • One combined rotation and revolution occurs every 18 minutes
  • Internal truss structure is comprised of 6,120 pieces of aluminum tubing
Eartha is a three-dimensional scale model of Earth with mountain and landform details, which rotates and revolves on a specially designed and built mechanized, cantilever arm and simulates the Earth?s real movements. DeLorme created Eartha by utilizing their mapping database, which is one of the largest in the world. When Eartha was first constructed, it was the first time in history that mapping data was put onto a sphere of this size.

Eartha is open for visitors Monday through Friday from 8am ? 5pm. Visitors are welcome to view Eartha from any one of the three floors.
The next time you're in Maine, please stop by and visit.
We're conveniently located on Route 1, right off Interstate 295 at exit 17, just south of L.L.Bean.
