  2. Meteoroid - Wikipedia

    en.wikipedia.org/wiki/Meteoroid

    Meteoroids travel around the Sun in a variety of orbits and at various velocities. The fastest move at about 42 km/s (94,000 mph) through space in the vicinity of Earth's orbit. This is escape velocity from the Sun, equal to the square root of two times Earth's speed, and is the upper speed limit of objects in the vicinity of Earth, unless they ...

    en.wikipedia.org/wiki/Meteor_air_burst

    Meteoroids enter the Earth's atmosphere from outer space traveling at speeds of at least 11 km/s (7 mi/s) and often much faster. Despite moving through the rarified upper reaches of Earth's atmosphere the immense speed at which a meteor travels rapidly compresses the air in its path.

    The travel time was determined by comparing the arrival times at the MINOS near- and far detector, apart from each other by 734 km. The clocks of both stations were synchronized by GPS, and long optical fibers were used for signal transmission. [11] They measured an early neutrino arrival of approximately 126 ns.

    The Massalia asteroid family, formed about 40 million years ago, accounts for a class of meteorites called L chondrites that represent 37% of known Earth meteorites, the research found.

    The fragments then entered dark flight (without the emission of light) and created a strewn field of numerous meteorites on the snow-covered ground (officially named Chelyabinsk meteorites). The last time a similar phenomenon was observed in the Chelyabinsk region was the Kunashak meteor shower of 1949, after which scientists recovered about 20 ...

    A meteorite crashed in the area of Mission, Texas, Wednesday night causing a loud boom that startled residents, authorities said.

  8. Meteorite - Wikipedia

    en.wikipedia.org/wiki/Meteorite

    Few meteorites are large enough to create large impact craters. Instead, they typically arrive at the surface at their terminal velocity and, at most, create a small pit. NWA 859 iron meteorite showing effects of atmospheric ablation The impact pit made by a 61.9-gram Novato meteorite when it hit the roof of a house on 17 October 2012.

  9. Meteorite fall statistics - Wikipedia

    en.wikipedia.org/wiki/Meteorite_fall_statistics

    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 distribution of types does not accurately reflect what falls to Earth.
