This exceptionally long and bright fireball was seen throughout the Yukon, Northern British Columbia, parts of Alaska, and the Northwest Territories.
Pieces of the 56-metric-ton meteorite rained down over a wide area of Canada on January 18, 2000, at approximately 16:43 UT (08:43 PST local).
Many pieces landed on the frozen Tagish Lake, allowing scientists to recover numerous samples. Studies show that the meteorite is intermediate in composition between the two most primitive groups of chondrite meteorites, CI and CM carbonaceous chondrites. The fireball was seen by many people and also detected by satellites in Earth orbit. Eye witnesses placed the duration of the fireball at about 15 seconds. The Observations of its trajectory allowed scientists to calculate its path through the solar system. The calculations show that it hails from the outer asteroid belt, in a place where dark, carbon- and water-rich asteroids reside. The meteorite is a new type of primitive meteorite that will surely shed light on how the solar system formed.
