On October 6, 2008, a small asteroid called 2008 TC3 was discovered by the automated Catalina Sky Survey 1.5 m telescope at Mount Lemmon, Tucson, Arizona, and found to be on a collision course with Earth. Numerous astronomical observatories followed the object until it entered the Earth's umbra at Oct. 7.076 UTC the next day. The astrometric position of 295 observations of 2008 TC3 over the period Oct. 6.278 to Oct. 7.063 was used to calculate the approach trajectory over the impact location in northern Sudan.

On Christmas Eve 1965, at about 4.20pm, residents of the large Leicestershire village heard sonic booms echo through the sky as the 100lb meteoroid broke up into pieces and landed in various unwelcome locations. The four billion-year-old rock scattered sporadically over a mile radius hitting cars, windows, factories and landing in fields.

In 1949, a collector named H.O. Stockwell discovered a mass of 450 kilograms (990 lb), known at the time as "The World's Largest Pallasite Meteorite." In October 2005, geologist Philip Mani and meteorite hunter Steve Arnold located and recovered the largest fragment ever found of Brenham: a single pallasite mass of 650 kilograms (1,430 lb).
In 1576, the governor of a province in Northern Argentina commissioned the military to search for a huge mass of iron, which he had heard that Natives used for their weapons. The Natives claimed that the mass had fallen from the sky in a place they called Piguem Nonralta which the Spanish translated as Campo del Cielo ("Field of Heaven").

The asteroid fell about 50,000 years ago. The meteorites have been known and collected since the mid-19th century and were known and used by pre-historic Native Americans. The Barringer Crater, from the late 19th to the mid-20th century, was the center of a long dispute over the origin of craters that showed little evidence of volcanism.

The Chelyabinsk meteorite is the fragmented remains of the large Chelyabinsk meteor of 15 February 2013 which reached the ground after the meteor's passage through the atmosphere. The descent of the meteor, visible as a brilliant superbolide in the morning sky, caused a series of shock waves that shattered windows, damaged approximately 7,200 buildings and left 1,500 people injured.

During 2007 fall and winter about 100 kilograms (220 lb) of meteorites were collected in the Erg Chech, north of Taoudenni. Desert nomads reported that during daytime in July 2007 several detonations were heard over a wide area, a smoke cloud was seen and several stones fell from the sky, however no fireball was reported.
On April 9, last, a brilliant meteor was seen at mid-day to fall in a northwesterly direction across northeastern Tennessee. Though the sun was shining in this section, observers describe the light from the meteor as exceeding the sun in brightness. Passing over southeastern Kentucky, where the sky was obscured by clouds, the meteor made its presence known by violent detonations, accompanied by the spalling off of fragments.

It had been reported that two meteorite showers occurred one month apart in 1960 in the country now known as Burkina Faso. But the new work confirms long-held suspicions that the two meteorites are indistinguishable from each other and that there was most likely only one fall (1960 March 5). The confusion about this meteorite has been compounded by the fact that new stones continue to be found ~40 years after the fall and are given arbitrarily one or the other name

The meteorite was discovered by the Nama people and used by them to make tools and weapons. In 1836 the English captain J. E. Alexander collected samples of the meteorite in the vicinity of the Great Fish River and sent them to London. There John Herschel analyzed them and confirmed for the first time the extraterrestrial nature of the material.

A mass of I ,250 g was purchased from Arab nomads by Captain Helo, a French officer serving in southern Algeria, in 1890. The meteorite was donated to the Museum d'Histoire Naturelle in Paris and was briefly described by Meunier (1892; 1893a: 40). According to Helo, the meteorite was observed to fall a few years earlier near an Arab tent camp which had been put up a few kilometers east of the Hassi-Jekna well.

According to Ait Hiba Abdelhad, a fireball was seen in the afternoon sky on December 16, 2012, several school children saw the fireball explode and detonations were heard near the village of Mehaires, Western Sahara. Pieces were recovered approximately 40 miles south of Mehaires, near Mreïra , Mauritania, only a few days after the event. The strewn field is in the area called "Stailt Omgrain", which is a local nomadic name. This is south of Mehaires and north of the mountain "Galbe lahmar". Therefore this is a possible fall associated with the fireball of December 16, 2012. Click the image for each individual specimen weight.

In 1931 this observed fall broke up in the atmosphere and fragments fell about 4 km Northeast of the village (Tatahouine) in total 12kg were collected, mostly in very small fragments. Subsequent searches have yielded more fragments. Tatahouine specimens do not have fusion crust.
Metallic spheroids approximately 1 mm in diameter and having a dendritic structure appropriate to a rapidly solidified liquid alloy are encountered in conjunction with Canyon Diablo meteorites in the vicinity of the Barringer crater, Arizona. Compositionally and structurally similar particles have been encountered in lunar soils returned from Apollo 11, 12, 14, and 15 expeditions. The present study is devoted entirely to Canyon Diablo spheroids, which are shown by means of electron microprobe techniques to be enriched in Ni and considerably enriched in S and P relative to the metallic phases of Canyon Diablo meteorites.
Four masses have been recovered: (1) 29 kg, (2) 25.2 kg, (3) 300 g, and (4) 18 kg, on the property of Mr. Wilson Rezende.

Muong-Nong type tektites, named for the site in Vietnam where they were first found, are centimetre- to decimetre-size objects and include the largest known tektites. They are chunky in form, often tablet-shaped, and often show layering, each of the layers being 1 mm or so in thickness.
Moldavite (Czech: Vltavín) is an olive-green or dull greenish vitreous substance formed by a meteorite impact.
The chemical formula of moldavite is SiO2(+Al2O3). Its properties are similar to that of other types of glass, and its Mohs hardness is 5.5. Moldavite can be transparent or translucent with a mossy green color, with swirls and bubbles accentuating its mossy appearance.
