The entry velocity of 20.95 km/s (46,900 mph) in the atmosphere was rapidly reduced by air resistance to about 2.4 km/s (5,400 mph) at the end of the visible trajectory. Then the meteorite went into free fall which lasted about 108 seconds. The impact velocity on the surface was about 250–280 km/h (160–170 mph).
The following structures are officially considered "unconfirmed" because they are not listed in the Earth Impact Database. Due to stringent requirements regarding evidence and peer-reviewed publication, newly discovered craters or those for which it is difficult to collect evidence are generally known for some time before becoming listed.
The traditional way of subdividing meteorites (see Meteorites classification) is into irons, stony-irons, and two major groups of stony meteorites, chondrites and achondrites. For some of the less-studied stony meteorite falls, it is not known whether the object is chondritic; thus the number of meteorites that can be so grouped is 4% lower ...

Velaidum reports that he was standing at that location minutes before the meteorite struck it; he considers the event "a near-death experience". [ 4 ] The meteorite came from the asteroid belt , according to the University of Alberta researcher, and would have traveled at least 200 kilometres per hour (124 mph) just prior to impact.
This is a list of largest meteorites on Earth. Size can be assessed by the largest fragment of a given meteorite or the total amount of material coming from the same meteorite fall: often a single meteoroid during atmospheric entry tends to fragment into more pieces. The table lists the largest meteorites found on the Earth's surface.
The Grand Canyon in Arizona is one of Earth's natural wonders, carved out over millions of years by the gradual erosion power of the Colorado River. Close to the moon's south pole are two canyons ...
NASA says four radar sweeps detected “signatures consistent with falling meteorites seen at the time and location reported by eyewitnesses,” and people also heard sonic booms. Museum offers ...
