Macula Polaznika ( Latin: Polaznik Macula ) - Macula (dark spot) on the surface of Titan , the largest satellite of Saturn . The maximum size is 350 km, the coordinates of the center are [1] .
This macula was found on infrared images taken by the Cassini spacecraft during a flight near Titan on January 28, 2010 (the designation of the flight is T66 [2] [3] ). It is named after Polyaznik - according to some versions of the myth, the Slavic god of New Year's happiness. This name was approved by the International Astronomical Union on April 5, 2010 [1] .
There are two lakes within the Macula Polaznika: 140-km lake Sionaskeyg and 30-km lake Urmia , and in the first there is an island. These are the first lakes discovered in the temperate zone of Titan. Perhaps the macula also contains lakes. There is an assumption that it is the bottom of a large carbohydrate, now almost dried up [2] [3] .
