Chondrules and calcium-rich inclusions (CAIs) are approximately 4.5 billion years old. This makes them the oldest known matter in existence on Earth, predating the formation of our own planet and even our Solar System. Carbonaceous chondrites comprise about 4% of all meteorites observed to fall from space. New micro-minerals are classified on meteorite CAIs on a regular basis, being studied nowadays by prestigious mineralogists around the world.
