Catch a shooting star and put it in your pocket? Not so simple. Welcome to the asteroid belt, the cosmic debris field between Mars and Jupiter. Here, millions of rocky bodies from pebble size to hundreds of miles wide dance in a chaotic ballet. Ever wonder how it came to be? The gravitational tug of Jupiter is to blame preventing these space rocks from coalescing into a planet. And did you know, despite its Hollywood depiction, the asteroid belt isn't densely packed? The average distance between two asteroids is a whopping five times the distance between Earth and the Moon. So next time you wish upon a star, remember, it might just be a lonely asteroid from our very own cosmic backyard.
