Shikoku Facula (Titan)

Japanese island.

Shikoku Facula is a region of bright material on Saturn's moon Titan. Shikoku was first seen in Cassini images taken in October 2004 and has been observed several times since. Before it provisionally received an official name in August 2005, this feature was nicknamed "Great Britain" due to its shape. This feature, 200×160 kilometers across, is within Titan's Shangri-La dark region and is centered at 10.4°S 164.1°W / -10.4; -164.1. (wikipedia entry)
