Would you believe our planet is made up of meteorites? The Earth is one big conglomeration of space debris collected over billions of years of Solar System formation starting with the birth of our Sun, and the formation of the Protoplanetary Disk around it.
In fact every planet that exists is made up of meteorites. Well, not really meteorites, but space debris. Meteorites are pieces of space debris which impact our planet, or any planet for that matter.
So for all you meteorite people out there, you should thank your meteorites for coming together and building the planet you live on today.
