The Wetumpka impact crater is the only confirmed impact crater in Alabama, United States.It is located east of downtown Wetumpka in Elmore County.The crater is 4.7 miles (7.6 km) in diameter, and its age is estimated to be about 85 million years (late Cretaceous), [1] based on fossils found in the youngest disturbed deposits, which belong to the Mooreville Chalk Formation.
An asteroid that crashed into the Earth’s atmosphere over the UK and France was spotted just hours before it crashed. ... It was the most powerful asteroid strike in more than 100 years, and ...
This list includes all 60 confirmed impact structures in North America in the Earth Impact Database (EID). These features were caused by the collision of large meteorites or comets with the Earth.
In 2021, evidence for a probable impact 3.46 billion-years ago at Pilbara Craton has been found in the form of a 150 kilometres (93 mi) crater created by the impact of a 10 kilometres (6.2 mi) asteroid (named "The Apex Asteroid") into the sea at a depth of 2.5 kilometres (1.6 mi) (near the site of Marble Bar, Western Australia).

Less than ten thousand years old, and with a diameter of 100 m (330 ft) or more. The EID lists fewer than ten such craters, and the largest in the last 100,000 years (100 ka) is the 4.5 km (2.8 mi) Rio Cuarto crater in Argentina. [2]
However, even during the asteroid’s closest pass to date on August 8 at about 352,300 miles (567,000 kilometers), it was nowhere near Earth’s Roche limit, said Carlos de la Fuente Marcos, a ...
The Weaubleau structure is a probable meteorite impact site in western Missouri near the towns of Gerster, Iconium, Osceola, and Vista. It is believed to have been caused by a 1,200-foot (370 m) meteoroid between 335 and 340 million years ago [ 1 ] during the middle Mississippian Period (Latest Osagean to Earliest Meramecian ).
Two NASA spacecraft at Mars — one on the surface and the other in orbit — have recorded the biggest meteor strikes and impact craters yet. The high-speed barrages last year sent seismic waves ...
