In the absence of a firm link between individual meteorites and their asteroidal parent bodies, asteroids are typically characterized only by their light reflection properties, and grouped accordingly into classes. On 6 October 2008, a small asteroid was discovered with a flat reflectance spectrum in the 554–995 nm wavelength range, and designated 2008 TC3 (refs 4–6). It subsequently hit the Earth. Because it exploded at 37 km altitude, no macroscopic fragments were expected to survive. Here we… 
The recovery of asteroid 2008 TC3
Abstract– On October 7, 2008, asteroid 2008 TC3 impacted Earth and fragmented at 37 km altitude above the Nubian Desert in northern Sudan. The area surrounding the asteroid’s approach path was
Asteroid 2008 TC3 and the Fall of Almahata Sitta, a Unique Meteorite Breccia
On October 6, 2008, the small (~4 m) asteroid 2008 TC 3 was discovered and predicted to hit Earth within ~19 hours. Photometric data and a reflectance spectrum were obtained. The asteroid fragmented
Photometric observations of Earth‐impacting asteroid 2008 TC3
Abstract– A calibrated lightcurve is presented of the near‐Earth asteroid 2008 TC3, obtained before it impacted Earth on October 7, 2008. The asteroid was observed in unfiltered images from the end
Exogenic basalt on asteroid (101955) Bennu
When rubble-pile asteroid 2008 TC 3 impacted Earth on 7 October 2008, the recovered rock fragments indicated that such asteroids can contain exogenic material 1 , 2 . However, spacecraft missions to
Small Near-Earth Asteroids as a Source of Meteorites
Small asteroids intersecting Earth's orbit can deliver extraterrestrial rocks to the Earth, called meteorites. This process is accompanied by a luminous phenomena in the atmosphere, called bolides or
Origin and history of ureilitic material in the solar system: The view from asteroid 2008 TC3 and the Almahata Sitta meteorite
Asteroid 2008 TC3 (approximately 4 m diameter) was tracked and studied in space for approximately 19 h before it impacted Earth's atmosphere, shattering at 44–36 km altitude. The recovered samples
Linking asteroids and meteorites to the primordial planetesimal population
The unusually frail asteroid 2008 TC3
Abstract The first asteroid to be discovered in space and subsequently observed to impact Earth, asteroid 2008 TC3, exploded at a high 37 km altitude and stopped ablating at 32 km. This would
The near-Earth asteroid (NEA) (175706) 1996 FG3 is a particularly interesting spacecraft target: a binary asteroid with a low-Δv heliocentric orbit. The orbit of its satellite has provided valuable


Compositional differences between meteorites and near-Earth asteroids
It is reported that most near-Earth asteroids (including the potentially hazardous subset) have spectral properties quantitatively similar to the class of meteorites known as LL chondrites, and the prominent Flora family in the inner part of the asteroid belt shares the same spectral properties, suggesting that it is a dominant source of near- Earth asteroids.
Mineralogical Variations within the S-Type Asteroid Class
Abstract A systematic spectral analysis has been Carried out on a large subset (39 of 144) of the S-type asteroid population. The S-asteroid class includes a number of distinct compositional subtypes
The flux of small near-Earth objects colliding with the Earth
Satellite records of bolide detonations in the atmosphere over the past 8.5 years are reported and it is found that the flux of objects in the 1–10-m size range has the same power-law distribution as bodies with diameters >50 m.
An entry model for the Tagish Lake fireball using seismic, satellite and infrasound records
Abstract— We present instrumental observations of the Tagish Lake fireball and interpret the observed characteristics in the context of two different models of ablation. From these models we estimate

The mid-infrared transmission spectra of Antarctic ureilites.
It was found that, while weathering of these meteorites produces some weak bands due to the formation of small amounts of carbonates and hydrates, the profile of the main silicate feature has been little affected by Antarctic exposure in the meteorites studied here.
