09. What Are Shooting Stars?

Country Available: Canada

Bob MacDonald

Rocks from space fall to Earth every day. Called meteoroids, these ‘rocks’ are mostly very small pebbles that drift our way from the asteroid belt beyond Mars. But every now and then a large object like a comet or asteroid strikes the Earth causing massive explosions that can wipe out life. We visit meteor crater, a giant hole in the ground created when a house sized object crashed to Earth fifty thousand years ago. We meet the astronomers who are searching the skies for other objects out there that could hit us in the future and look at plans to do something about it if one of them is heading our way. So grab your hard-hat, we’re taking you outside to see for yourself…
