You may never visit outer space, but here are some interesting facts about it. Outer space is not completely empty, but is made up of a vacuum with many particles, including plasma, hydrogen, helium, electromagnetic radiation, magnetic fields and more. There is no real boundary where the atmosphere ends and space begins, but areas are still defined. One popular boundary, the Kármán line, places it at 62 mi (100 km) above sea level. This area is in the thermosphere, where space stations orbit. Past the thermosphere is the exosphere, the highest level yet defined. But, let's get back to space itself. In space, there is no friction, allowing things like planets and stars to simply move along freely in their orbits. Matter is still existent in the vacuum of space, but there is a low density of matter. To show this, let's put it this way: In space, per cubic meter, there are a few atoms of hydrogen. On Earth, there are 10,000,000,000,000,000,000,000,000 atoms of hydrogen in the air we breath per cubic meter. That's amazing!
