Scientists Uncover Secret , Behind the Strange Behavior , of Earthbound Meteorites.
'The Independent' reports that scientists now understand why rocks survive entry into the Earth's atmosphere as meteorites.

Most of our meteorites fall from rocks the size of grapefruits to small cars, Peter Jenniskens, lead author and meteor astronomer at SETI Institute and Nasa Ames Research Center, via 'The Independent'.
Rocks that big do not spin fast enough to spread the heat during the brief meteor phase, and we now have evidence that the backside survives to the ground, Peter Jenniskens, lead author and meteor astronomer at SETI Institute and Nasa Ames Research Center, via 'The Independent'.
A 6-meter asteroid detected in 2008 helped researchers more fully understand meteorites.
.
Scientists tracked the asteroid for over 20 hours before it hit Earth's atmosphere.
The impact created a bright meteor that disintegrated over the Nubian Desert of Sudan and ended with a shower of meteorites.

In a series of dedicated search campaigns, our students recovered over 600 meteorites, some as big as a fist, but most no bigger than a thumbnail, Muawia Shaddad, University of Khartoum professor, via 'The Independent'.

Friction in the atmosphere stopped the smallest meteorites from reaching Earth, while larger pieces survived the fall.
The largest meteorites from 2008 TC3 were spread wider than the small ones, which means that they originated from this final collapse, Peter Jenniskens, lead author and meteor astronomer at SETI Institute and Nasa Ames Research Center, via 'The Independent'.
Based on where they were found, we concluded that these pieces stayed relatively large all the way to the ground, Peter Jenniskens, lead author and meteor astronomer at SETI Institute and Nasa Ames Research Center, via 'The Independent'.
The team's findings were published in 'Meteoritics and Planetary Science.'
