What are some notable impact events?
An impact event is a collision between astronomical objects causing measurable effects. Impact events have been found to regularly occur in planetary systems, though the most frequent involve asteroids, comets or meteoroids and have minimal effect.
An impact event is a collision of astronomical objects, such as asteroids, comets, or meteoroids, with planets or moons. Learn about the history, effects, and types of impact events, from the Vredefort Dome to the Chicxulub crater, and how they are studied by NASA.
Sentry is a highly automated collision monitoring system that continually scans the most current asteroid catalog for possibilities of future impact with Earth over the next 100 years. Whenever a potential impact is detected it will be analyzed and the results immediately published here, except in unusual cases where we seek independent ...
Feb 15, 2021 · A new theory by Harvard researchers suggests that the asteroid or comet that hit Earth 66 million years ago and wiped out the dinosaurs was a fragment of a larger object that broke apart near the sun. They use statistical analysis and gravitational simulations to explain the origin and frequency of such impact events.
How did the asteroid that hit Earth 66 million years ago cause mass extinction and global chaos? Learn about the tsunamis, heat pulse, impact winter, and other effects of the Cretaceous-Paleogene boundary.
Jun 26, 2019 · Learn how NASA scientists used modern computer modeling and data from the 1908 Tunguska and 2013 Chelyabinsk events to reexamine the frequency and effects of mid-size asteroid impacts on Earth. Find out how the new results challenge previous estimates and improve our understanding of the asteroid population and defense.
Sep 14, 2022 · Learn how asteroids and comets have shaped Earth's history and geology, from the Moon's formation to the dinosaur extinction. Discover the evidence and effects of past and recent impact events, and the science behind them.
