Selk is a crater on Titan, a moon of Saturn, located at 7°N 199°W. It is a geologically young impact crater that measures approximately 90 kilometres (56 mi) in diameter.[1]
There is evidence of the past presence of organic compounds and liquid water in the crater, which is set to be studied in the planned Dragonfly mission.[2] The initial landing site will be in the dunes to the Southeast of Selk.[3]
The crater is named after Serket, a goddess in Egyptian mythology, and was formally approved by the IAU in 2008.[4]
