Where do meteorites come from?

[Still Waters]

If asked where meteorites come from, you might reply “from comets”. But according to our new research, which tracked hundreds of fireballs on their journey through the Australian skies, you would be wrong.

In fact, it is very likely that all meteorites — space rocks that make it all the way to Earth — come not from icy comets but from rocky asteroids. Our new study found that even those meteorites with trajectories that look like they arrived from much farther afield are in fact from asteroids that simply got knocked into strange orbits.

We searched through six years’ worth of records from the Desert Fireball Network, which scans the Australian outback for flaming meteors streaking through the sky. None of what we found came from comets.
