Argyre Planitia is a circular, vast plain on the southern hemisphere of the planet Mars . Your name is derived from ancient Greek and means something like "silver plane". Argyre Planitia is the third largest impact basin on Mars after Hellas Planitia and Isidis Planitia .

description
Argyre Planitia was formed about 3.9 billion years ago, during the early geological history of the planet, by the impact of an asteroid . The impact basin has a diameter of about 900 km and lies on average 5 km below the surrounding regions. The bottom of the basin has several large impact craters , the largest of which, Martian Hooke Crater ( 44 ° 55 ′ S , 44 ° 24 ′ W ) on its northern edge, has a diameter of 138 km. In the middle of the elevations of the eastern rim of the crater , on the border to Noachis Terra, lies the 224 km large Galle impact crater ( 50 ° 38 ′ S , 31 ° 0 ′ W ). In addition, relatively sharply defined rock formations rise from the plain.
