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).

2024 YR 4 is an asteroid with an estimated diameter of 40 to 90 metres (130 to 300 ft) that is classified as an Apollo-type (Earth-crossing) near-Earth object.From 27 January to 20 February 2025, it had an impact rating of 3 on the Torino scale, with a maximum estimated probability of 3.1% that it would impact Earth on 22 December 2032.
The last record holder was Asteroid Apophis in 2004, which briefly had a 2.7% chance of impact. Since its discovery, Asteroid 2024 YR4 has warranted international attention, and large telescopes ...
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 ...

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.
