De meeste daarvan bevinden zich ten zuiden van de evenaar. Ze lijken te zijn ontstaan doordat meteorieten miljarden jaren geleden op het oppervlak zijn neergestort. De grootste krater heeft een diameter van ongeveer 1800 km \u2013 groot genoeg om de helft van Europa te verzwelgen.<\/p>\n<\/div>\n<p>Het oppervlak van Mars is in de loop van zijn bestaan echter veranderd. Een opvallend kenmerk is het enorme stelsel van valleien \u2013 de Valles Marineris \u2013 nabij de evenaar van de planeet. Met een lengte van ongeveer 5000 km zouden deze zich uitstrekken van Parijs tot New York.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1467\" data-credit=\"ESA\/DLR\/FU Berlin (G.
