Canals View ( Latin Vid Flumina ) is a system of canals on Titan , through which, probably, liquid hydrocarbons flow - mainly methane and ethane .
Geography and geology
The center has coordinates [1] . The maximum size is 158 km [1] , the width is less than 0.8 km, the depth is 240-570 m [2] . View channels are the largest and most complex active river system discovered outside the Earth . Due to the similarity in shape and size to the terrestrial river Nile , the Vid canals received the nickname "second Nile", "mini-Nile" [3] . Despite the fact that the canals have small meanders (smooth bends of the river bed), the titanium analogue of the “Nile” has a direct river bed - this means that it flows at the fault point in the soil of Titan . The river network stretches 400 kilometers from the source and flows into the Kraken Sea [3] . According to pictures of the channel located in the region of the North Pole of Titan, scientists have come to the conclusion that it is filled with a fluid fluid. This is supported by the fact that the surface of the main channel looks dark and characteristically smooth along its entire length [3] . This is confirmed by a later (2016) analysis of the Cassini radar data obtained in 2013, when it was used as an altimeter [2] .
Eponym
The canal system is named after the wide icy and poisonous river of the Elivagar system in Scandinavian mythology [1] . The name was approved by the International Astronomical Union in 2013 [1] .
