Hellas Planitia
A Mars Orbiter Laser Altimeter (MOLA) image (onboard the Mars Global Surveyor orbiter) of Hellas Planitia.
Hellas Planitia is a vast meteorite impact basin located at 42° 42'S 70° 00'E, in the Mars southern hemisphere. Also known as the Hellas Impact Basin, this landmark has a very obvious impact crater ring 2,300 km (1,400 mi) in diameter. This is one of the largest known impact craters in the solar system.[1][2]
The basin floor is about Template:Convert deep, Template:Convert deeper than the Moon's South Pole-Aitken basin, and extends about Template:Convert east to west.[3][4] Hellas Planitia is in the Hellas quadrangle and the Noachis quadrangle.
