The difference between asteroids, meteorites and meteors. Enjoy!

In simplest terms here are the definitions:

Asteroid: a large rocky body in space, in orbit around the Sun.

Meteoroid: much smaller rocks or particles in orbit around the Sun.

Meteor: If a meteoroid enters the Earth's atmosphere and vaporizes, it becomes a meteor, which is often called a shooting star.

Meteorite: If a small asteroid or large meteoroid survives its fiery passage through the Earth's atmosphere and lands on Earth's surface, it is then called a meteorite.

Asteroids
  • Most asteroids in our solar system are found in the main asteroid belt, a region between Mars and Jupiter. But they can also hang out in other locations around the solar system. For example, some asteroids orbit the Sun in a path that takes them near Earth.

Meteoroids

Space debris smaller than an asteroid are called meteoroids. A meteoroid is a piece of interplanetary matter that is smaller than an asteroid and frequently are only millimeters in size. Most meteoroids that enter the Earth's atmosphere are so small that they vaporize completely and never reach the planet's surface. When they burn up during their descent, they create a beautiful trail of light known as a meteor, sometimes called a shooting star.

Meteorite

If any part of a meteoroid survives the fall through the atmosphere and lands on Earth, it is called a meteorite. Although the vast majority of meteorites are very small, their size can range from about a fraction of a gram (the size of a pebble) to 100 kilograms (220 lbs) or more

Summary

In short, the difference between asteroids and meteors all comes down to a question of location. Asteroids are always found in space. Once it enters an atmosphere, it becomes a meteor, and then a meteorite after it hits the ground. Each are made of the same basic materials – minerals and rock – and each originated in space. The main difference is where they are when they are being observed.

IC 2118 also known as Witch Head Nebula is a dark nebula close the the star of Rigel, which is part of the Orion constelation. The light of this blue star is reflected by the nebula and creates this face like shape.

And everyone you love is made of stardust, and I know sometimes you cannot even breathe deeply, and the night sky is no home, and you have cried yourself to sleep enough times that you are down to your last two percent, but nothing is infinite, not even loss. You are made of the sea and the stars, and one day you are going to find yourself again.”
