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.
The EID lists fewer than ten such craters, and the largest in the last 100,000 years (100 ka) is the 4.5 km (2.8 mi) Rio Cuarto crater in Argentina. [2] However, there is some uncertainty regarding its origins [ 3 ] and age, with some sources giving it as < 10 ka [ 2 ] [ 4 ] while the EID gives a broader < 100 ka.
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.
Lake Siljan is a large part of the southwest edge of the much-eroded crater. Lonar Lake in India. An impact crater lake is a lake inside a depression caused by the impact of a meteor. It is also known as an annular lake in cases where the water body is shaped like a ring, as many impact crater lakes are.
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 ...
Lonar Lake lies within the only known extraterrestrial impact crater found within the great Deccan Traps, a huge basaltic formation in India. [22] The lake was initially believed to be of volcanic origin, but now it is recognized as an impact crater. Lonar Lake was created by the impact of either a comet or of an asteroid.
The Siljan Ring (Swedish: Siljansringen) is a prehistoric impact structure in Dalarna, central Sweden. [1] It is one of the 15 largest known impact structures on Earth and the largest in Europe, with a diameter of about 52 kilometres (32 mi).
