Canadian meteorite may be first visitor from the Kuiper belt
A fireball that streaked through the sky over a decade ago may have brought the first meteorite from the outskirts of the solar system.
Most meteorites found on Earth are thought to start out in the asteroid belt, which lies between Mars and Jupiter, but the makeup of the Tagish Lake meteorite, which fell on an icy lake in Canada’s British Columbia in 2000, bears little resemblance to other space rocks.
That might be because it formed much further out in the Kuiper belt, the ring of icy bodies beyond Neptune that has Pluto as its most famous member. NASA recently approved an extension of the New Horizons mission to visit a Kuiper-belt object called 2014 MU69, so having a sample of similar material on Earth could help us understand how this region of the solar system formed.
