The Asteroid Terrestrial-impact Last Alert System, or ATLAS, telescope in Rio Hurtado, Chile, first discovered 2024 YR4 on December 27. The telescope is one of the asteroid discovery programs ...
The rock was discovered on Dec. 27, 2024, by the NASA-funded Asteroid Terrestrial-Impact Last Alert System (ATLAS) telescope in Chile. The size, trajectory, and speed of the asteroid immediately ...
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. [22] The most probable impact angle is 45 degrees. [22] Impact conditions such as asteroid size and speed, but also density and impact angle determine the kinetic energy released in an impact event.
This is a list of asteroids that have impacted Earth after discovery and orbit calculation that predicted the impact in advance. As of December 2024, all of the asteroids with predicted impacts were under 5 m (16 ft) in size that were discovered just hours before impact, and burned up in the atmosphere as meteors.
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.
"An asteroid this size impacts Earth on average every few thousand years and could cause severe damage to a local region," the European Space Agency said. An asteroid could hit Earth in 2032, NASA ...
"An asteroid this size impacts Earth on average every few thousand years and could cause severe damage to a local region," the ESA said a previous statement about 2024 YR4.. If the asteroid does ...
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.
