The impactor's velocity was estimated at 20 kilometers per second (12 mi/s). [30] The kinetic energy of the impact was estimated at 72 teratonnes of TNT (300 ZJ). [ 31 ] The impact generated winds in excess of 1,000 kilometers per hour (620 mph) near the blast's center, [ 32 ] and produced a transient cavity 100 kilometers (62 mi) wide and 30 ...
Meteorite fall statistics are frequently used by planetary scientists to approximate the true flux of meteorites on Earth. Meteorite falls are those meteorites that are collected soon after being witnessed to fall, whereas meteorite finds are discovered at a later time. Although there are 30 times as much finds than falls, their raw ...
There are several lists of meteorite impacts of various types available: Category:Lists of impact craters contains lists on various planets, including Earth by continent; Meteorite falls are observed; Meteorite finds are rocks found on the ground which are geologically identified as meteorites; Meteorite contains lists of the most notable of ...
In this dramatic illustration, a meteor falls toward Earth from space. A pair of asteroids that rammed into Earth more than 35 million years ago seemingly had no climate impacts, scientists said ...
The average near-Earth asteroid, such as 2019 VF 5, passes Earth at 18 km/s. The average short-period comet passes Earth at 30 km/s, and the average long-period comet passes Earth at 53 km/s. [8] A retrograde parabolic Oort cloud comet (e=1, i=180°) could pass Earth at 72 km/s when 1 AU from the Sun.
Harvard researchers found that when a meteorite nicknamed S2 paid a visit to our planet 3 billion years ago, it may have helped life flourish.
The meteorite, S2, was first discovered in 2014. It hit the planet about 3.26 billion years ago and is estimated to have been up to 200 times larger than the space rock that later killed the ...
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 [update] , 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 .
