The Federated States of Micronesia is an independent republic associated with the United States. It consists of four states – from west to east, Yap, Chuuk, Pohnpei and Kosrae – that are spread across the Western Pacific Ocean. Together, the states comprise around 607 islands that cover a longitudinal distance of almost 2,700 km (1,678 mi) just north of the equator. They lie northeast of New Guinea, south of Guam and the Marianas, west of Nauru and the Marshall Islands, east of Palau and the Philippines, about 2,900 km (1,802 mi) north of eastern Australia, 3,400 km southeast of Japan, and some 4,000 km (2,485 mi) southwest of the main islands of Hawaii.
