Eartha, the World's Largest Revolving and Rotating Globe

Eartha DeLorme's world record holding globe

Eartha, the world's largest rotating and revolving globe, is located within the headquarters of the DeLorme mapping corporation in Yarmouth, Maine. The globe weighs approximately 5,600 pounds (2,500 kg), and has a diameter of over 41 feet (12.5 m). This gives it a scale of 1:1,000,000, on which one inch represents 16 miles (26 km), one millimeter represents one kilometer. As with most globes, it's mounted at a 23.5 degree angle, the same axial tilt as the Earth itself; thus the equator is diagonal to the floor. It uses a cantilever mount with two motors, and simulates one day's revolution and rotation every hour, though it is possible for the motors to fully rotate the globe in as little as one minute.
