Canso is a Martian crater. It lies about 450 kilometres west of the Viking 1 lander, slightly northeast of Lunae Planum, and west of Chryse Planitia, in the Lunae Palus quadrangle. The crater is named after Canso, a fishing town in Nova Scotia. The name was officially adopted in 1988 by the International Astronomical Union's Working Group for Planetary System Nomenclature (IAU/WGPSN).
Impact craters generally have a rim with ejecta around them, in contrast volcanic craters usually do not have a rim or ejecta deposits. As craters get larger (greater than 10 km in diameter) they usually have a central peak.[1] The peak is caused by a rebound of the crater floor following the impact.[2]
