A meteoroid that survives falling through the Earth’s atmosphere and colliding with the Earth’s surface is known as a meteorite. The fastest meteoroids travel through the Solar system at a speed of around 42 kilometers per second. A small percentage of meteoroids fly on a path that goes into the Earth’s atmosphere and then back out again, they are known as Earth grazing fireballs. The Earth’s atmosphere experience millions of meteors everyday. When many meteors occur in a close time frame in the same part of the sky,it is called a meteor shower.
