What is actually happening when I see a 'shooting star'?

You are seeing a rock burn up in the atmosphere as it falls down towards the ground. Most rocks will disintegrate into dust as they fall and never actually reach the ground. The rocks are moving up to 50 miles per second, so as it stars to hit the air, the air heats up and burns the rock.

Many rocks come from the kuiper belt. It's the area beyond pluto where tons of tiny rocks, dust and more dwarf planets are. As they are nudged and run into each other, some fall out of orbit and into the middle part of solar system, running into earth.
