Chang’e-4 Probe Explores One of the Largest Impact Craters in the Solar System

The Chang’e-4 probe is exploring the Von Kármán crater which located within the much larger South Pole-Aitken (SPA) Basin. It was likely formed by a giant impact early in the Moon’s history. The crater is over 2,500 kilometers (1,550 miles) in diameter and 13 kilometers deep. It is one of the largest impact craters in the Solar System and the largest.

The deepest part of the Earth is in the Ocean at the Mariana trench. The deepest part of the trench is the Challenger Deep at 10,994 meters (36,070 feet) below sea level.
