Meteors Meaning and Definition in Wikipedia
A meteor is what you see when a space rock falls to Earth. It is often known as a shooting star or falling star and can be a bright light in the night sky, though most are faint. If it hits the ground, it is then called a meteorite and it will leave a hole in the ground called a crater. Meteoroids may range in size from large pieces of rock to tiny dust particles floating in space that did not form planets. Once the meteoroids enter Earth's atmosphere and begin to heat up and break apart, they are known as meteors. Meteors are distinct from comets or asteroids, but some, especially those associated with showers, are dust particles that were ejected from comets.
There are several types of meteorites including: stony, carbonaceous chondrites, and iron-nickel. Stony meteorites are named because they are largely made up of stone-like mineral material, carbonaceous chondrites have a high carbon content and iron-nickel meteorites are mostly iron often with significant nickel as well.[See more about Meteors at Dictionary 3.0 Encyclopedia]
