Due to Earth's escape velocity, the minimum impact velocity is 11 km/s with asteroid impacts averaging around 17 km/s on the Earth. [19] The most probable impact angle is 45 degrees. [19] Impact conditions such as asteroid size and speed, but also density and impact angle determine the kinetic energy released in an impact event.
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.
2024 UQ, designated formerly as A11dc6D, was a one-meter meteoroid that struck the Earth's atmosphere and burned up harmlessly on 22 October 2024 above the Pacific Ocean off the coast of California. 2024 UQ is the tenth impact event that was successfully predicted, which was discovered by the ATLAS survey.
In all, the asteroid’s impact was only the seventh time that such an event has been predicted in advance. ... It was the most powerful asteroid strike in more than 100 years, and left around ...
A meteor that exploded in a spectacular fireball over Niagara Falls in 2022 was the smallest asteroid ever measured, a new study has found.. The asteroid, spotted by astronomers just hours before ...
A meteor exploded over New York City in the middle of the day, according to Nasa and local reports.. At around 11.17am local eastern time, a fireball appears to have flown over Manhattan and then ...
The Chicxulub impact has been widely considered the most likely cause for the Cretaceous–Paleogene mass extinction, with some scholars linking other impacts like the Popigai impact in Russia and the Chesapeake Bay impact to later extinction events, though the causal relationship has been questioned.

The asteroid brightened to about apparent magnitude 15 (about the brightness of Pluto) before disappearing into Earth's shadow. [1] It is the sixth successfully-predicted asteroid impact. [9] [b] With an absolute magnitude of 33.6, it is the smallest asteroid discovered while it was in space. [14]
