Eponym Kraken

Kraken Mare is the largest known body of liquid on the surface of Saturn's moon Titan. It was discovered in 2007 by the Cassini probe and was named in 2008 after the Kraken, a legendary sea monster.[1]

At 400,000 km²,[2] Kraken Mare is believed to be the largest of numerous seas and lakes in Titan's north polar region.[1] Its status as a sea of hydrocarbons was identified by radar imagery. Kraken Mare is believed to be larger than the Caspian Sea on Earth.

An island in the sea is named Mayda Insula. Kraken Mare may be hydrologically connected to the second-largest sea on Titan, Ligeia Mare.

The narrow constriction in the sea at 317°W, 67°N, about 17 km wide and similar in size to the Strait of Gibraltar, has been termed the 'Throat of Kraken' and suggested to be a location of significant currents.[3] Titan's orbital eccentricity may lead to tides of 1 m in Kraken Mare, generating currents here of 0.5 m/s and possibly whirlpools.[4]

As part of the proposed Titan Saturn System Mission, a probe would splash down on Kraken Mare in order to scrutinize its composition, depth and numerous other properties.
