Aitken (crater) The South Pole–Aitken basin (SPA Basin, / ˈeɪtkɪn /) is an immense impact crater on the far side of the Moon. At roughly 2,500 km (1,600 mi) in diameter and between 6.2 and 8.2 km (3.9–5.1 mi) deep, it is one of the largest known impact craters in the Solar System. It is the largest, oldest, and deepest basin recognized Chesapeake Bay Crater. Size: 53 miles wide. Location: Virginia, USA. Age: 35 million years. Nearby Landmark: Rappahannock River. Source: wikimedia.org. Considered to be one of the best-preserved “wet-target” impact craters in the world, the Chesapeake Bay Crater is the largest known impact site in the United States. The following year, MacGregor et al. (2019) report the discovery of a possible second subglacial impact crater around 36.5-km wide and 183 km southeast of the Hiawatha impact crater. Based on satellite and aerogeophysical data, they suggest the identified structure is likely an impact crater, although this is not yet confirmed by direct The Earth Impact Database (EID) comprises a list of confirmed impact structures from around the world. To date, there are 190 confirmed impact structures in the database. The database was conceived in its earliest form when a systematic search for impact craters was initiated in 1955 by the Dominion Observatory, Ottawa, under the direction of The Operational Land Imager (OLI) on Landsat 8 acquired this image of the area on May 16, 2021. Even at 50,000 years old, the crater is relatively young and remarkably well-preserved compared to other craters. Because of this, scientists have studied the site extensively to learn about cratering processes—how they work on Earth and elsewhere There are only about 185 known impact craters on Earth of any age, while the moon has more than 100,000. But the number of Ordovician craters may soon take off. dZmSLLU. Johnsonville crater. /  33.817°N 79.367°W  / 33.817; -79.367. The Johnsonville crater or the Snow's Island crater is a circular geophysical feature situated at the junction of the Lynches River and the Pee Dee River in South Carolina, United States, which has been interpreted by some scientists as an impact crater. June 30, 2016 6:00 AM EDT. O n June 30th, 1908, an asteroid entered the Earth’s atmosphere above Tunguska, Siberia and exploded with the energy of about 185 Hiroshima-level atomic bombs. In The crater is just the second impact crater ever found in China and adds to the 190 known craters worldwide. 10.1111/maps.13711. NASA: Young Impact Crater Secondary cratering on Earth: The At 31 km across, the Hiawatha impact crater is larger than about 90% of the roughly 200 previously known impact craters on Earth. Although the Hiawatha impact crater is much smaller than the The 812 separate images were sewn together using Drone to Map software by DJI and ESRI ARCMAP GIS Programs. Cordier, C.
