Hellas Planitia is a vast meteorite impact basin located at 42° 42'S 70° 00'E, in the Mars southern hemisphere. Hellas Planitia is in the Hellas quadrangle and the Noachis quadrangle. 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]
