Scientists are tracking the fireball onto a strange rocky meteoroid from the Oort Cloud

A rocky meteoroid that exploded over Canada last year was more extraordinary than it first appeared: it came from the outer solar system, where scientists thought only icy bodies existed.

A cavalcade of professional and amateur astronomers captured images and video of it meteoroid when it exploded over Alberta. By examining this data, the researchers determined that the meteoroid broke apart like a rocky object and survived deeper earth atmosphere than icy objects on similar trajectories. However, the analysis also suggested that the meteoroid originated from the Oort cloudmore than Pluto. The discovery of a body of rock from this region could rewrite existing theories as to how the solar system educated.
