Why So Many Meteorites Come From The Same Place
Because of space physics, one faraway asteroid is likely the progenitor of almost a third of all the meteorites on Earth. Thanks to Skillshare for sponsoring this video: http://skl.sh/MinuteEarth...

Hi, this is Emily from MinuteEarth. Over the ages, the million or so rocks that make up the main asteroid belt between Mars and Jupiter have sent chunks of space debris large and small crashing into Earth. And after analyzing a lot of these meteorites, we've discovered something really weird: more than a third of them have the same chemical signature, suggesting that they've broken off from a single asteroid. By using special telescopes to look at the mineral makeup of asteroids, we think we’ve identified the culprit, known as Hebe. Hebe is pretty big compared to other asteroids in the asteroid belt, but it still only makes up a tiny fraction of the total mass. And it’s been in lots of meteoroid-making collisions - including one violent en...
