An asteroid is an extra terrestrial body made of rock or metal… or both.

They come in all sizes. Some are as small as a potato; others are like mini planets, as big as a whole country.

Most of them orbit the sun between Mars and Jupiter and form a ring called the “asteroid belt”.

Where do they come from?

The solar system was formed out of a swirl of gas, dust and ice particles.

These tiny particles joined together bit by bit to form bigger and bigger rocks, until they became planets.
