There is a vast amount of rocks and debris floating around in space.

You might have been lucky enough to have seen

Is it a comet?, meteorite? Maybe an asteroid?

Astronomers believe they are leftovers from the early formation

of the solar system that reside in one of two places

on the very outskirts of the solar system;

These two areas are made up of small icy bodies

of frozen gases such as methane, ammonia,

nitrogen and water mixed with rock and dust.

Occasionally a comets orbit will be altered by a

gravitational tug of another large object

or through a collision with another body that might

or sometimes even straight towards the sun.

it heats up and ice starts to evaporate and form a cloud around the nucleus, called the coma.

Two tails form as well, the ion tail and the dust tail.

is made from the dust forming around the nucleus

it is being pushed by solar radiation from the sun

and points directly away from the solar winds coming from the sun.

Nearly all Asteroids are odd shaped chunks of rock that orbit the sun

n the asteroid belt between mars and Jupiter.

The asteroid belt is thought to be either left over mass

due to the close gravitational pull of Jupiter

or the leftovers from a planet that broke up due to a collision.

Sizes vary from 10 meters to 1000 kilometers wide

and big enough to be classed as a dwarf planet.

Some asteroids also have their own moons!

Space debris smaller than 10 meter asteroids are called meteoroids.

They are usually bits of asteroids that have collided or leftover debris from a comet.

When a meteoroid enters earths atmosphere it will hurtle towards Earth

and creates a dazzling trail of light due to the air resistance it encounters.

or as we sometimes call them, shooting stars.

When a rock is large enough to survie entry

It will end up hitting the Earths surface, usually the size of a pebble.

Found in Namibia, that fell 80,000 years ago.

the Earth's orbit takes us through the dust and debris

and creates an incredible display of shooting stars

You can find out more about this and how to view the spectacle in the link at the end of the video or in the description below.
