À propos de cet e-book

Have you ever seen a shooting star? What you really saw was a meteor! A meteor is actually a chunk of metallic or stony matter – called a meteoroid – that enters the earth’s atmosphere from outer space. A comet, on the other hand, is a lump of ice and dust that periodically comes into the center of the solar system from somewhere in its outer reaches. Learn more about meteors and comets in this lively and informative book!
