How far is Memphis from Okinawa?

The question is non-sensical because Memphis is a city in the state of Tennessee in the United States, while Okinawa is the name of a group of islands located approximately 30° north of the Tropic of Cancer that comprise Okinawa Prefecture, the southernmost prefecture of Japan. As Memphis and Okinawa are in different countries located across an ocean they do not have a distance between them but rather a separation. The straight line distance (as the crow flies) between them is approximately 8,062 mi.
