Impact event. Damage to trees caused by the Tunguska event. The object, just 50–80 metres (150–240 feet) across, exploded 6–10 km (4–6 miles) above the surface, shattering windows hundreds of km away. An impact event is a collision between astronomical objects causing measurable effects. [1]
99942 Apophis (provisional designation 2004 MN4) is a near-Earth asteroid and a potentially hazardous object with a diameter of 370 metres (1,210 feet) [3] that caused a brief period of concern in December 2004 when initial observations indicated a probability up to 2.7% that it would hit Earth on April 13, 2029.
The small near-Earth asteroids 2008 TC 3, 2014 AA, 2018 LA, 2019 MO, 2022 EB 5, 2022 WJ 1, 2023 CX 1, 2024 BX 1, and 2024 RW 1 are the only nine asteroids discovered before impacting into Earth (see asteroid impact prediction). Scientists estimate that several dozen asteroids in the 6–12 m (20–39 ft) size range fly by Earth at a distance ...
Area. 30,000 ha (120 sq mi) The Vredefort impact structure is the largest verified impact structure on Earth. [1] The crater, which has since been eroded away, has been estimated at 170–300 kilometres (110–190 mi) across when it was formed. [2][3] The remaining structure, comprising the deformed underlying bedrock, is located in present-day ...
This is a list of asteroids that have impacted Earth after discovery and orbit calculation that predicted the impact in advance. As of January 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.
Free-air gravity anomaly over the Chicxulub structure (coastline and state boundaries shown as black lines) The Chicxulub crater (IPA: [t͡ʃikʃuˈluɓ] ⓘ cheek-shoo-LOOB) is an impact crater buried underneath the Yucatán Peninsula in Mexico. Its center is offshore, but the crater is named after the onshore community of Chicxulub Pueblo ...
The minimum orbit intersection distance (MOID) between an asteroid and the Earth is the distance between the closest points of their orbits. This first check is a coarse measure that does not allow an impact prediction to be made, but is based solely on the orbit parameters and gives an initial measure of how close to Earth the asteroid could ...
Map all coordinates using OpenStreetMap. This list of impact structures on Earth contains a selection of the 190 confirmed craters given in the Earth Impact Database. [1] To keep the lists manageable, only the largest impact structures within a time period are included. Alphabetical lists for different continents can be found under Impact ...
