Comparison of approximate sizes of notable impactors with the Hoba meteorite, a Boeing 747 and a New Routemaster bus. The Hoba meteorite left no preserved crater and its discovery was a chance event. In 1920, [1] the owner of the land, Jacobus Hermanus Brits, encountered the object while ploughing one of his fields with an ox. While working the ...
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.
It is the largest meteorite found in the United States and the sixth largest in the world. [ 6 ] [ 7 ] There was no impact crater at the discovery site; researchers believe the meteorite landed in what is now Canada or Montana , and was transported as a glacial erratic to the Willamette Valley during the Missoula Floods at the end of the last ...
The largest in the last one million years is the 14-kilometre (8.7 mi) Zhamanshin crater in Kazakhstan and has been described as being capable of producing a nuclear-like winter. [11] The source of the enormous Australasian strewnfield (c. 780 ka) is a currently undiscovered crater probably located in Southeast Asia. [12] [13]
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 collections.
In total, approximately 100 tonnes of fragments have been recovered, the most of any meteorite finding. [3] [4] The two largest fragments, the 30.8-tonne Gancedo and 28.8-tonne El Chaco, are among the heaviest single-piece meteorite masses recovered on Earth, following the 60-tonne Hoba meteorite and a 31-tonne fragment of the Cape York meteorite.
A more recent reference states that the meteorite is an iron meteorite belonging to Group IIAB, which can be classified as either a hexahedrite or a coarsest octahedrite. [3] Chemical analysis showed that the material contained 6.3% nickel (Ni), 0.5% Phosphorus (P), 53.9 parts per million (ppm) Gallium (Ga), 141 ppm Germanium (Ge), and 0.02 ppm ...
Lonar Lake, also known as Lonar crater, is a saline, soda lake, located at Lonar, 79 km from Buldhana city in Buldhana district, Maharashtra, India. It is a notified National Geo-heritage Monument. [2] [3] [4] Lonar Lake is in an impact crater created by a meteorite impact during the Pleistocene Epoch.
