Midway Atoll is a 6.2 sq km (2.4 sq mi) atoll in the North Pacific Ocean. As its name suggests, Midway is roughly equidistant between North America and Asia, and lies almost halfway around the world from Greenwich, England. It is near the northwestern end of the Hawaiian archipelago, about one-third of the way from Honolulu, Hawaii to Tokyo, Japan. Photo courtesy of NASA.
