Ironically, the most carbon-rich bodies in the solar system are not the Sun or the planets, but smaller bodies such as comets and asteroids, leftover planetary building blocks that have escaped collisions with planets or ejection from solar orbits for more than 4 billion years, Snow and Brownlee write.
And despite its relative rarity here on Earth, carbon’s ability to bond with elements to form a nearly infinite number of compounds is likely why we are here to talk about it. But could life in our solar system have gone a different way and be based on an element like silicon, instead of carbon?
