Today's lesson - The difference between Meteors, meteorites, and meteoroids (and asteroids and comets too)

Following on from yesterday's news about the brand spanking new meteorite crater in south west Egypt (5,000 years old is fairly new if you're a 4 billion year old planet), I thought it would be nice and informative of me to explain the difference between a meteor, a meteorite, a meteoroid, a comet and an asteroid.
Now if you're a cosmochemist (greatest job title in the world (unless of course you're Envoy Extraordinary and Minister Plenipotentiary http://tiny.cc/6r4m2 (or a Rouge Dragon Pursuivant of Arms in Ordinary http://tiny.cc/irqa4))) you'll know the difference between a meteor and a meteorite and all that other space jazz, but if you're not then here it is: -

Asteroid: An asteroid is a relatively small (relative to a planet that is, but still sometimes 21 miles long) inactive celestial body composed of rock, carbon or metal that orbits the sun.
They sometimes gather in clusters called Asteroid belts, the closest asteroid belt is in-between Mars and Jupiter.
Interesting fact, Earth should be regularly pummelled by asteroids due to the gravitational pull of the Sun but is prevented by the huge mass of Jupiter

Comet: Similar to Asteroids, comets are relatively small but mostly comprised of rock and Ice. They highly recognisable and distinguished by the Dust and Gas tails seen trailing behind them when they're close to the sun. 
If you want to see the most famous comet, Halley's comet the next time it makes an appearance, make sure you're not busy or dead 28 July 2061.

Meteoroid: A meteoroid comes from an asteroid and is a small particle that orbits the sun. they can be fairly big, but mostly they're tiny bits of space debris.

This is a meteor, they're frickin' awesome!

Meteor: A meteor starts out as an asteroid, they're space rocks that enter Earth's atmosphere and get burned up by particles surrounding earth which leave spectacular trails behind them. In fact - The term meteor comes from the Greek meteoron, meaning phenomenon in the sky.

Meteorite: Most meteorites don't look this kick ass, but occasionally they do and mess loads of stuff up, like our poles for instance, our poles used to be nice and regular, till a big ol' meteorite turned up and knocked us of our axis and gave us our seasons. 
This picture shows the point where a meteor stops being a meteor and becomes a meteorite, when it hits a planet.
Meteorites are so big they don't burn up when they enter Earth's atmosphere, they just plough straight and make craters and excite cosmochemists and physics teachers.
