Big Old Crater

October 26, 2009
On August 28, 2000, the camera on NEAR Shoemaker took this picture of Eros' limb from an orbital altitude of 100 kilometers (62 miles). The two craters near the top left part of the frame are about 2.2 kilometers and 1.6 kilometers (1.4 miles and 1 mile) in diameter, respectively. The top large crater is thought to be relatively old because many smaller craters have been superimposed on its rim and interior--an indication that it has been subjected to a very long period of bombardment by impacting meteors. The whole scene is about 3 kilometers (1.8 miles) across.
