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 Hoba meteorite is thought to have impacted Earth less than 80,000 years ago. It is inferred [4] that the Earth's atmosphere slowed the object in such a way that it impacted the surface at terminal velocity, thereby remaining intact and causing little excavation (expulsion of earth). Assuming a drag coefficient of about 1.3, the meteor ...
Less than ten thousand years old, and with a diameter of 100 m (330 ft) or more. 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]
The Vredefort impact structure is the largest verified impact structure on Earth. [1] The crater, which has since been eroded away, has been estimated at 170–300 kilometres (110–190 mi) across when it was formed.
Cape York – One of the largest meteorites in the world. A 34-ton fragment called "Ahnighito", is exhibited at the American Museum of Natural History; the largest meteorite on exhibit in any museum. Gibeon – A large Iron meteorite in Namibia, created the largest known strewn field. Hoba – The largest known intact meteorite.
The Cape York meteorite, also known as the Innaanganeq meteorite, is one of the largest known iron meteorites, classified as a medium octahedrite in chemical group IIIAB. [5] In addition to many small fragments, at least eight large fragments with a total mass of 58 tonnes have been recovered, the largest weighing 31 tonnes (31 long tons; 34 ...
The Winchcombe meteorite is a rare find, with a similar hydrogen isotope ratio to the water on Earth.. Recovering a meteorite within 12 hours of arrival means it is as pristine a specimen as we ...
The Aletai meteorite, previously also known as the Armanty meteorite or Xinjiang meteorite, is one of the largest known iron meteorites, classified as a coarse octahedrite in chemical group IIIE-an. [b] In addition to many small fragments, at least five main fragments with a total mass over 74 tonnes have been recovered, the largest weighing about 28 tonnes.
