The Kamchatka superbolide is estimated to have had a mass of roughly 1600 tons, and a diameter of 9 to 14 meters depending on its density, making it the third largest asteroid to impact Earth since 1900, after the Chelyabinsk meteor and the Tunguska event. The fireball exploded in an airburst 25.6 kilometres (15.9 mi) above Earth's surface.
A meteorite is a portion of a meteoroid or asteroid that survives its passage through the atmosphere and hits the ground without being destroyed. [22] Meteorites are sometimes, but not always, found in association with hypervelocity impact craters ; during energetic collisions, the entire impactor may be vaporized, leaving no meteorites.
A "meteorite fall", also called an "observed fall", is a meteorite collected after its arrival was observed by people or automated devices. Any other meteorite is called a "meteorite find". [ 43 ] [ 44 ] There are more than 1,100 documented falls listed in widely used databases, [ 45 ] [ 46 ] [ 47 ] most of which have specimens in modern ...
There is broad consensus that the Chicxulub impactor was a C-type asteroid with a carbonaceous chondrite-like composition, rather than a comet. [ 29 ] [ 67 ] These types of asteroids originally formed in the outer Solar System, beyond the orbit of Jupiter . [ 67 ]
These features were caused by the collision of meteors (consisting of large fragments of asteroids) or comets (consisting of ice, dust particles and rocky fragments) with the Earth. For eroded or buried craters, the stated diameter typically refers to the best available estimate of the original rim diameter, and may not correspond to present ...
An impact winter is a hypothesized period of prolonged cold weather due to the impact of a large asteroid or comet on the Earth's surface. If an asteroid were to strike land or a shallow body of water, it would eject an enormous amount of dust, ash, and other material into the atmosphere, blocking the radiation from the Sun. This would cause ...

Bolide from the French astronomy book Le Ciel; Notions 'Elémentaires d'Astronomie Physique (1877). The word bolide (/ ˈ b oʊ l aɪ d /; from Italian via Latin, from Ancient Greek βολίς (bolís) 'missile' [2] [3]) may refer to somewhat different phenomena depending on the context in which the word appears, and readers may need to make inferences to determine which meaning is intended in ...
