Craters on asteroid 433 Eros

Craters on asteroid 433 Eros

. The many craters on the surface of the asteroid 433 Eros are attributed to eons of collisions with other asteroids. Large boulders, perhaps broken off Eros during these impacts, are perched on one of the crater’s edge. The largest boulder, on the horizon in the center of the picture, is about 40 meters long. The two overlapping craters shown here were probably formed many millions of years apart. This picture, taken on 7 July 2000 from the NEAR Shoemaker spacecraft, is 1.8 kilometers wide.
