The fireball and sonic boom which were seen and heard from western Navada to the Sacramento Valley on
22 April 2012, were caused by a minivan-sized meteorite. Numerous fragments have been found composed of the very rare substance carbonaceous chondrite which is older than the sun. Only about 1 percent of meteorites are composed of this substance, which can fetch as much as $ 1 000 a gram on the open market.
