Meteors

A meteor shower occurs when a number of meteors flash seem to radiate (or shoot out from) the same point in the sky. They are usually named for the constellation in which their radiant appears. The meteoroids in a shower usually come from the trail of debris left behind by a comet. In the case of the Geminids and Quadrantids, those meteor showers come from the debris scatted by orbiting asteroids. When Earth’s orbit intersects the dust trail, we see more meteors flaring as the cometary debris encounters our planet’s atmosphere.
A meteor is a bright streak of light in the sky (a "shooting star" or a "falling star") produced by the entry of a small meteoroid into the Earth's atmosphere. If you have a dark clear sky you will probably see a few per hour on an average night; during one of the annual meteor showers you may see as many as 100/hour.

A meteoroid is a small rock or particle of debris in our solar system. They range in size from dust to around 10 meters in diameter (larger objects are usually referred to as asteroids).
THANK
YOU
FOR
WATCHING
Martian meteorite is a rock that formed on the planet Mars and was then ejected from Mars by the impact of an asteroid or comet, and finally landed on the Earth
An asteroid striking our planet -- it's the stuff of science fiction. Many movies and books have portrayed this possibility ("Deep Impact," "Armageddon," "Lucifer's Hammer," and so on).
An asteroid impact is also the stuff of science fact. There are obvious craters on Earth (and the moon) that show us a long history of large objects hitting the planet. The most famous asteroid ever is the one that hit Earth 65 million years ago. It's thought that this asteroid threw so much moisture and dust in to the atmosphere that it cut off sunlight, lowering temperatures worldwide and causing the extinction of the dinosaurs.
So, what if an asteroid were to hit Earth today?
And now the journey ends. We hope you've learned that asteroids comets and meteorites may appear the same when seen billions of miles away, but each are unique. We hop you can take the facts you've learned and recognize that the shooting star you saw was not really a star but a meteor, or that the ball of light with a long tail is not a shooting star but an orbiting comet. These objects orbit around the sun just like the planets, yet their orbits are much larger and different and more commonly have some that break out and head to earth, the sun, or other planets in the galaxy.
Do you think you can now tell which is which?
1. Comet(Notice the tail!) 2. Asteroid(see the craters) 3. Meteor(Its burning up as it enters the atmosphere)
