which the solar wind carries outward to form into a long tail.

All of the planets and the Sun are round, like balls.

Short-period comets that complete their orbits in less than 200 years are thought to originate from the disk-shaped Kuiper Belt, while long-period comets that take more than 200 years to return are thought to come from the spherical Oort Cloud.

There is a lot of difference between the planets.

Jupiter and Saturn have each been visited by several spacecraft, and were also host to long-term missions including Juno and Galileo at Jupiter, and Cassini at Saturn. Uranus and Neptune

Some planets like Earth are made of rock, and some like Jupiter are made of gas.

The hottest planet is Venus where the average temperature is 460°C, and the coldest is Uranus, which is -220°C.

Mars is sometimes the called ‘the red planet’ because the rocks that it is made from are red.

It is the closest planet to Earth, and is slightly smaller than Earth.

The biggest planet is Jupiter.

Jupiter is made of gas and is so big that you could fit 1,321 planets the size of Earth inside it.

There is even a storm on Jupiter that is bigger than Earth – this storm has been blowing for hundreds of years and is called the ‘Great Red Spot’.

saturn is famous for having rings of small pieces of ice and dust around it. Like Jupiter, it is made of gas and is much bigger than Earth.

The Moon is a ball of rock that orbits around the Earth,

the same way that the Earth orbits around the Sun.

It is much smaller than the Earth and takes 28 days to complete one orbit.

Earth is the only planet on which we know that there have been plants and animals living.

were nine planets in the Solar System.

he ninth planet was Pluto and it is even further away from the Sun than Neptune

Astronomers decided that Pluto was too small to be called a planet, so now there are only eight planets.
