You asked us, "How much stuff is in orbit around the Earth. And is it dangerous?"
NASA tracks some half a million pieces of space junk. They track everything from bits of useless satellites to the random lost glove. Or even a spatula.
The United States Department of Defense tracks everything larger than a softball. There are about 20,000 objects.
Why? Because a piece of space junk that size is moving at about 10 times the speed of a bullet. It will hit you with the power of 25 sticks of dynamite.
Worse, when space junk runs into other space junk, it doesn't just fall into earth's atmosphere and burn up.
It becomes millions of little missiles racing around the earth. That's instead of two big ones.
Thank goodness we can always count on a little help from our friends.
Take the Chinese, for example. In 2007, they decided to show off their fancy new anti-satellite missile system. And they blew up an old weather satellite. It added another 3,000 pieces of killer junk to the problem.
On the upside, our mates in Australia are working on a laser to zap space junk out of orbit.
