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.
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 Asteroid Terrestrial-impact Last Alert System (ATLAS) first noted this asteroid. Due to 2024 UQ being close to the boundary between two adjacent fields, [clarification needed] [4] only hours later was the object reported to be moving. By then, the asteroid had already impacted Earth.
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]
2024 BX 1 is the eighth asteroid discovered before impacting Earth, and is Sárneczky's third discovery of an impacting asteroid. Before it impacted, 2024 BX 1 was a near-Earth asteroid on an Earth-crossing Apollo-type orbit. The bolide was studied in June 2024. It had a steep entry of 75.6° and an entry speed of 15.20 km/s.
2023 DW is a near-Earth asteroid of the Aten group.It is approximately 50 meters (160 feet) in diameter, roughly the size of the asteroid that caused the Tunguska event, [a] and was discovered by Georges Attard and Alain Maury, from the MAP (Maury/Attard/Parrott) asteroid search program in San Pedro de Atacama on 26 February 2023, when it was 0.07 AU (10 million km) from Earth.

The Torino scale is a method for categorizing the impact hazard associated with near-Earth objects (NEOs) such as asteroids and comets.It is intended as a communication tool for astronomers and the public to assess the seriousness of collision predictions, by combining probability statistics and known kinetic damage potentials into a single threat value.
