The Unisphere is a giant stainless steel globe perched in Flushing Meadows-Corona Park in Queens, New York. The US Steel Corporation built it as a symbol of world peace for the 1964-1965 World's Fair. The Unisphere is 140 feet high and 120 feet in diameter. It weighs 900,000 pounds. Since the continents are the heaviest parts of the all-steel sculpture and they aren't evenly distributed, the Unisphere is top heavy. It was carefully engineered to account for the unbalanced mass. The Unisphere has remained popular among visitors, soccer players, museum and theater goers, Mets fans, and locals.
