Mayda Insula is an island in the Kraken Mare, a body of liquid composed primarily of methane, on Saturn's largest moon Titan. Mayda Insula is the first island (insula) to be named on a planet or moon other than Earth.
Discovery and naming
Mayda Insula was discovered by the Cassini–Huygens mission to Saturn. Its name was approved by the International Astronomical Union Working Group for Planetary System Nomenclature on April 11, 2008, becoming the first named island on a planetary body other than earth, and the largest. NASA notes, however, that the possibility Mayda Insula is actually peninsular (i.e., connected to the mainland by a strip of land) cannot be conclusively ruled out. All of the insulae on Titan have been named for legendary islands and "Mayda Insula" was derived from the legendary island Mayda which was thought to exist in the northeastern Atlantic Ocean. Its name was approved the same day as the names of Kraken Mare and Ligeia Mare.
Mayda Insula lies in the northern end of the Kraken Mare near Titan's north pole. The island has a northernmost latitude of 80.3 degrees north and a southernmost latitude of 77.4 degrees north; it has a westernmost longitude of approximately 321.2 degrees west and an easternmost longitude of 302.7 degrees west. The island is 168 kilometres (104 mi) wide at its widest point. Its dimensions are approximately 90 by 150 kilometres (56 by 93 mi), about the same size as the Big Island of Hawaii.
The highest point of the interior of Mayda Insula is approximately 1,200 metres (3,900 ft) above its shoreline. Slopes are relatively mild at approximately 1.5 degrees on average, though they can approach 5 degrees in some locations. Radar images of Titan's surface show that Mayda Insula's coasts display evidence of being changed by fluvial and lacustrine processes. Analyses of these fluvial features suggested that approximately 2 km3 of material has been eroded from Mayda Insula and deposited elsewhere in the Kraken Mare basin.
