In late 2019 the Kiso Observatory added a new instrument to the telescope, "Tomo-e Gozen", designed to detect fast moving and rapidly changing objects. It has a wide field of view (20 square degrees ) and scans the sky in just 2 hours, far faster than any other survey as of 2021.
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. [4] [2]
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 ...

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 ...
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.
99942 Apophis (provisional designation 2004 MN 4) is a near-Earth asteroid and a potentially hazardous object, 450 metres (1,480 ft) by 170 metres (560 ft) in size, [3] that caused a brief period of concern in December 2004 when initial observations indicated a probability of 2.7% that it would hit Earth on Friday, April 13, 2029.
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 ...
