The Wold Cottage meteorite (also called the Wold Newton meteorite) fell near Wold Cottage farm in 1795, a few miles away from the village of Wold Newton in Yorkshire, England.
The stone fell at around 3 o'clock, on 13 December 1795, landing within a few yards of ploughman John Shipley.[2] It created a crater approximately 1 yard (0.91m) across, and embedded itself in the underlying chalk rock to a depth of 7 inches (180mm), passing through 12 inches (300mm) of topsoil. The fall was observed by several people, who described a dark body passing through the air.[3] As discovered at its landing point, the stone was warm and smoking; several people reported sounds of explosions as it fell.[4] The owner of the land was MajorEdward Topham, a well-known public figure, an ex-soldier, playwright and newspaper proprietor; he publicised the find and exhibited the meteorite publicly at Piccadilly in London.[5][6]
Early analyses recorded two parts of the stone, an earthy part, and a malleable part. The earthy part analysed as containing silicon, magnesium, iron, and a small amount of nickel, of which some parts of the iron and nickel were in the elemental state; the earthy substance was similar to kaolin (weathered feldspar), but relatively tough. The malleable parts also contained iron and nickel, the majority iron. A form of iron pyrites (iron sulphur compound) was also reported present.[9][10] Modern science records the meteorite as a L6 ordinary chondrite.[1]
The Wold Cottage meteorite was the largest meteorite observed to fall in Britain, and is the second-largest recorded in Europe (after the Ensisheim meteorite).[5] The meteorite and evidence given about its fall contributed to the debate concerning whether extraterrestrial matter existed or not, and towards the early scientific study of meteorites.[11][12][13]
A monument was erected on the location of the stone's impact, by Major Topham, on whose property the stone had fallen.[14] The structure was built of brick 4ft (1.2m) square and 25ft (7.6m) high, with a plaque on one face.[15]
In fiction
The event was used by the science fiction writer Philip José Farmer in his "biographies" of fictional characters (Tarzan Alive and Doc Savage: His Apocalyptic Life) as the basis for a literary premise commonly referred to as the Wold Newton family. The film Robinson in Ruins would also refer to the event, with the main character, Robinson, seeing it showing meteorites always fall at the time of significant events, in this case the 1795 amendment to the Settlement Act which allowed capitalism to develop faster in England.
The meteorite plays quite a central role in the 2019 detective novel Sherlock Holmes & The Christmas Demon by British author James Lovegrove.

Kamacite is an alloy of iron and nickel, which is found on Earth only in meteorites. According to the International Mineralogical Association (IMA) it is considered a proper nickel-rich variety of the mineral native iron. The proportion iron:nickel is between 90%:10% and 95%:5%; small quantities of other elements, such as cobalt or carbon may also be present. The mineral has a metallic luster, is gray and has no clear cleavage although its crystal structure is isometric-hexoctahedral. Its density is about 8 g/cm3 and its hardness is 4 on the Mohs scale. It is also sometimes called balkeneisen.
A meteorite is a rock that originated in outer space and has fallen to the surface of a planet or moon. When the original object enters the atmosphere, various factors such as friction, pressure, and chemical interactions with the atmospheric gases cause it to heat up and radiate energy. It then becomes a meteor and forms a fireball, also known as a shooting star; astronomers call the brightest examples "bolides". Once it settles on the larger body's surface, the meteor becomes a meteorite. Meteorites vary greatly in size. For geologists, a bolide is a meteorite large enough to create an impact crater.
Ernst Florens Friedrich Chladni was a German physicist and musician. His most important work, for which he is sometimes labeled as the father of acoustics, included research on vibrating plates and the calculation of the speed of sound for different gases. He also undertook pioneering work in the study of meteorites and is regarded by some as the father of meteoritics.
A chondrite is a stony (non-metallic) meteorite that has not been modified, by either melting or differentiation of the parent body. They are formed when various types of dust and small grains in the early Solar System accreted to form primitive asteroids. Some such bodies that are captured in the planet's gravity well become the most common type of meteorite by arriving on a trajectory toward the planet's surface. Estimates for their contribution to the total meteorite population vary between 85.7% and 86.2%.
James Sowerby was an English naturalist, illustrator and mineralogist. Contributions to published works, such as A Specimen of the Botany of New Holland or English Botany, include his detailed and appealing plates. The use of vivid colour and accessible texts was intended to reach a widening audience in works of natural history. The standard author abbreviation Sowerby is used to indicate this person as the author when citing a botanical name.
A micrometeorite is a micrometeoroid that has survived entry through the Earth's atmosphere. Usually found on Earth's surface, micrometeorites differ from meteorites in that they are smaller in size, more abundant, and different in composition. The IAU officially defines meteoroids as 30 micrometers to 1 meter; micrometeorites are the small end of the range (~submillimeter). They are a subset of cosmic dust, which also includes the smaller interplanetary dust particles (IDPs).
Carbonaceous chondrites or C chondrites are a class of chondritic meteorites comprising at least 8 known groups and many ungrouped meteorites. They include some of the most primitive known meteorites. The C chondrites represent only a small proportion (4.6%) of meteorite falls.
The ordinary chondrites are a class of stony chondritic meteorites. They are by far the most numerous group, comprising 87% of all finds. Hence, they have been dubbed "ordinary". The ordinary chondrites are thought to have originated from three parent asteroids, with the fragments making up the H chondrite, L chondrite and LL chondrite groups respectively.
The Tagish Lake meteorite fell at 16:43 UTC on 18 January 2000 in the Tagish Lake area in northwestern British Columbia, Canada.
Heazlewoodite, Ni3S2, is a rare sulfur-poor nickel sulfide mineral found in serpentinitized dunite. It occurs as disseminations and masses of opaque, metallic light bronze to brassy yellow grains which crystallize in the trigonal crystal system. It has a hardness of 4, a specific gravity of 5.82. Heazlewoodite was first described in 1896 from Heazlewood, Tasmania, Australia.
Mbozi is an ungrouped iron meteorite found in Tanzania. It is one of the world's largest meteorites, variously estimated as the fourth-largest to the eighth-largest, it is located near the city of Mbeya in Tanzania's southern highlands. The meteorite is 3 metres (9.8 ft) long, 1 metre high, and weighs an estimated 16 metric tons.
CI chondrites, also called C1 chondrites or Ivuna-type carbonaceous chondrites, are a group of rare carbonaceous chondrite, a type of stony meteorite. They are named after the Ivuna meteorite, the type specimen. CI chondrites have been recovered in France, Canada, India, and Tanzania. Their overall chemical composition closely resembles the elemental composition of the Sun, more so than any other type of meteorite.
The Chinga meteorite is an iron meteorite. It is structurally an ataxite with very rare kamacite lamella. The meteoric iron is a part of the lamella taenite. The total chemical composition is 82.8% iron, 16.6% nickel, and the rest mostly cobalt and phosphorus.
Lodranites are a small group of primitive achondrite meteorites that consists of meteoric iron and silicate minerals. Olivine and pyroxene make up most of the silicate minerals. Like all primitive achondrites lodranites share similarities with chondrites and achondrites.
Winonaites are a group of primitive achondrite meteorites. Like all primitive achondrites, winonaites share similarities with chondrites and achondrites. They show signs of metamorphism, partial melting, brecciation and relic chondrules. Their chemical and mineralogical composition lies between H and E chondrites.
The Zakłodzie meteorite is a stony-iron meteorite found in Poland in 1998. Its mass is 8.68 kilograms (19.1 lb). It is composed predominantly from enstatite and meteoric iron. Currently classified as an ungrouped enstatite achondrite its classification is still an ongoing scientific debate.
The Itqiy meteorite is an enstatite-rich stony-iron meteorite. It is classified as an enstatite chondrite of the EH group that was nearly melted and is therefore very unusual for that group. Other classifications have been proposed and are an ongoing scientific debate.
This is a glossary of terms used in meteoritics, the science of meteorites.
CM chondrites are a group of chondritic meteorites which resemble their type specimen, the Mighei meteorite. The CM is the most commonly recovered group of the 'carbonaceous chondrite' class of meteorites, though all are rarer in collections than ordinary chondrites.
Gas-rich meteorites are meteorites with high levels of primordial gases, such as helium, neon, argon, krypton, xenon and sometimes other elements. Though these gases are present "in virtually all meteorites," the Fayetteville meteorite has ~2,000,000 x10−8 ccSTP/g helium, or ~2% helium by volume equivalent. In comparison, background level is a few ppm.
