Hellas Planitia /ˈhɛləs pləˈnɪʃiə/ is a plain located within the huge, roughly circular impact basin Hellas[lower-alpha 1] located in the southern hemisphere of the planet Mars.[3] Hellas is the third- or fourth-largest known impact crater in the Solar System. The basin floor is about 7,152 m (23,465 ft) deep, 3,000 m (9,800 ft) deeper than the Moon's South Pole-Aitken basin, and extends about 2,300 km (1,400 mi) east to west.[4][5] It is centered at 42.4°S 70.5°E / -42.4; 70.5.[3] It features the lowest point on Mars, serves as a known source of global dust storms, and may have contained lakes and glaciers.[6] Hellas Planitia spans the boundary between the Hellas quadrangle and the Noachis quadrangle.
