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]
The Earth Impact Database is a database of confirmed impact structures or craters on Earth. It was initiated in 1955 by the Dominion Observatory , Ottawa, under the direction of Carlyle S. Beals . Since 2001, it has been maintained as a not-for-profit source of information at the Planetary and Space Science Centre at the University of New ...
Asteroid designation Date of impact Location of impact Method of detection Estimated size Reference 2008 TC 3: October 7, 2008: Nubian Desert in Sudan: visual, weather satellite, meteorite recovery: 4 m (13 ft) [1] 2014 AA: January 2, 2014: Central Atlantic Ocean: infrasound: 2–4 m (6.6–13.1 ft) [2] 2018 LA: June 2, 2018: Botswana/South ...
The small asteroid, measuring about a metre across, did not pose a threat to life. It was the third space rock detected imminently before impacting the Earth this year, but only the tenth on record.
The news about the discovery of the world’s largest asteroid impact crater is huge, if true—323-miles-in-diameter huge.. Researchers at University New South Wales (UNSW) believe they’ve ...
For example, the Ishim impact structure [141] is conjectured to be bounded by the late Ordovician-early Silurian (c. 445 ± 5 Ma), [142] the two Warburton basins have been linked to the Late Devonian extinction (c. 360 Ma), [310] both Bedout and the Wilkes Land crater have been associated with the severe Permian–Triassic extinction event (c ...
Asteroid impact prediction is the prediction of the dates and times of asteroids impacting Earth, along with the locations and severities of the impacts. The process of impact prediction follows three major steps: Discovery of an asteroid and initial assessment of its orbit which is generally based on a short observation arc of less than 2 weeks.
A man planning a camping trip using Google Maps ran across a uniquely curved spherical pit in Quebec. It may be an ancient asteroid impact crater. ... Of the world’s roughly 200 impact craters ...
