Geography and geology
The crater coordinates are [1] . Located northwest oflight area Dilmun . To the north of it is the Richez Maze , and to the south is the 80-km Selk Impact Crater. The emissions formed during the impact mainly cover only the surrounding area of the crater, its rim is widely penetrated by grooves [3] . The crater bottom is flat and contains a small central peak formed upon impact [3] .
To date, the Cassini spacecraft, located in the orbit of Saturn, is exploring the surface of Titan as it approaches it, thanks to this it was possible to confirm the presence of ten large craters on its surface (as of April 2015).
The dense atmosphere of Titanium from nitrogen prevents the formation of a crater with a diameter of less than 20 km, because a meteorite during a fall manages to burn out in the atmosphere without reaching the surface. In 2007, it was announced that over the next seven years Cassini will radar the surface of the Titan, and expressed hope for the discovery of new craters in connection with the mapping of about 50% of its surface [4] .
Eponym
The crater is named after the Maori goddess of knowledge and creation Afekan [1] . This name was approved by the International Astronomical Union in 2008 [1] .
