What is the largest crater on the moon? Discoveries of recent, datable impact craters like these establish the present-day impact cratering rate on the Moon, which will lead to better understanding of the bombardment rate in the inner solar system. It may be overtopped however by the Wilkes Land Crater in Antarctica (500 km), if the origin of this l crater will be proved. *This post may contain affiliate links. The largest impact events found on Earth are puny compared to other craters found in the solar system. This is the largest of all the impact craters on Earth, measuring 250-300 km diameter. The crater is located in a region called the Amazonis Planitia and is estimated to stretch 490 feet across and at least 70 feet deep, with some of the materials from the impact being thrown as far . The crater was initially discovered all the way back in 1974 by the Mariner Spaceprobe however, at the time only half of the crater was pictured. Of course considering how the crater covers around 40% of Iapetus diameter, it wouldnt be surprising that shortly after that Turgis was seen. List of largest craters in the Solar System. 0 1 . For comparison, it is bigger than Mercury and Pluto, and three-quarters the size of Mars. It is about 170 miles (275 kilometers) in diameter.
