Early Meteorite Bits Reveal Clues About Solar System's Evolution

Many meteorites found on Earth are remnants of one titanic solar-system collision that took place more than 460 million years ago. But for the first time, researchers have specifically targeted meteorites that fell to Earth just before that asteroid collision and found that the composition of those earlier space rocks is quite different than those today.

You would think that everything within the heliosphere's grasp would have similar metallic properties as these materials can withstand the heat of the solar wind which is why icy, celestal bodies can't withstand such a close radius with the Sun or were slingshoted out of the solar system via Jupiter; hence, such icy bodies manifest near the edge of the solar system bordering the kuiper belt onwards. Which would make sense since the Heavy Bombardment period occurred 4 to 3.8 ga that gives the solar system enough time to stabilize itself overall.

Nevertheless, I guess we all learn something new everyday. lol
