The 60-tonne, 2.7 m-long (8.9 ft) Hoba meteorite in Namibia is the largest known intact meteorite.[1]A meteorite is a rock that originated in outer space and has fallen to the surface of a planet or moon.
A Martian meteorite is a rock that formed on Mars, was ejected from the planet by an impact event, and traversed interplanetary space before landing on Earth as a meteorite. As of September 2020 [update] , 277 meteorites had been classified as Martian, less than half a percent of the 72,000 meteorites that have been classified. [ 1 ]
A meteorite is a portion of a meteoroid or asteroid that survives its passage through the atmosphere and hits the ground without being destroyed. [77] Meteorites are sometimes, but not always, found in association with hypervelocity impact craters; during energetic collisions, the entire impactor may be vaporized, leaving no meteorites.
Pieces of Mars rock can command similar prices, with a 4.25-pound piece selling for $63,000, approximately $15,000 per pound. Meteorites from the Moon are even more valuable. A 406-gram lunar ...
Ordinary chondrites are by far the most common type of meteorite to fall to Earth: about 80% of all meteorites and over 90% of chondrites are ordinary chondrites. [11] They contain abundant chondrules, sparse matrix (10–15% of the rock), few refractory inclusions, and variable amounts of Fe–Ni metal and troilite (FeS). Their chondrules are ...
Within this rock is an Earth meteorite (lunar sample 14321,1027) that is 4 billion years old. Big Bertha on the lunar surface prior to collection. It is above the exact center of the photo and lies between the wheel tracks made by the Modular Equipment Transporter (MET) or rickshaw-type portable workbench.
The rock is not from outer space, Wilson insisted. “I debunked that story by escorting a geology professor from the University of Akron to Glendale,” Wilson wrote in 1991.
Eucrites are achondritic stony meteorites, many of which originate from the surface of the asteroid 4 Vesta and are part of the HED meteorite clan. They are the most common achondrite group with over 100 meteorites found. Eucrites consist of basaltic rock from the crust of 4 Vesta or a similar parent body.
