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.
Non-metallic meteorites that lack chondrules are achondrites, which are believed to have formed more recently than chondrites. [5] There are currently over 27,000 chondrites in the world's collections. The largest individual stone ever recovered, weighing 1770 kg, was part of the Jilin meteorite shower of 1976. Chondrite falls range from single ...
Chondrules form as molten or partially molten droplets in space before being accreted to their parent asteroids. Because chondrites represent one of the oldest solid materials within the Solar System [ 1 ] and are believed to be the building blocks of the planetary system, it follows that an understanding of the formation of chondrules is ...

That makes them one of the most metal-rich of any of the chondrite groups, second only to the CB chondrites and some ungrouped chondrites such as NWA 12273. The first meteorite discovered was ALH 85085. Chemically, these chondrites are closely related to CR and CB groups. All specimens of this group belong only to petrologic types 2 or 3. [11]
The structures form due to the precipitation of a single crystal phase into two separate phases. In this way, the Widmanstätten transformation differs from other transformations, such as a martensite or ferrite transformation. The structures form at very precise angles, which may vary depending on the arrangement of the crystal lattices.
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.
