Combined, they make up the largest known impact zone on Earth, but individually, are smaller than the largest in the world, the 300 km wide Vredefort impact structure in South Africa. The Warburton craters formed when an asteroid or comet, on a collision course with Earth, split into two main pieces and impacted the Australian continent , [ 2 ...
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 ...
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).

The most infamous asteroid impact occurred 66 million years ago, when a six-mile-wide space rock triggered a global winter, wiping out the dinosaurs and 75% of all species. By contrast, 2024 YR4 ...
For now, NASA astronomers have sketched out a very general 2024 YR4 impact zone running from the eastern Pacific Ocean to northern South America, the Atlantic coast of Africa, the Arabian Sea, and ...
A new simulation looked at what would happen if the Earth collided with an asteroid with a diameter of around 500 metres, roughly the same as Bennu, a real rock that has been studied in great ...
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]
While still an extremely low possibility, asteroid 2024 YR4's impact probability with Earth has increased from about 1% to a 2.3% chance on Dec. 22, 2032. As we observe the asteroid more, the ...
