What is the Solar System?

The Solar System is made up of our star, called the Sun, and everything that travels, or orbits, around it. This includes eight planets and their moons, dwarf planets, asteroids, comets, and smaller bits of rock and dust. The Solar System is one of many solar systems that exist in the Universe.

Asteroids

Asteroids are lumps of rock and metal left over from when the Solar System first formed. Most can be found in the asteroid belt, which is located between the planets Mars and Jupiter.

Gas planets

The four outer planets – Jupiter, Saturn, Uranus and Neptune – are the largest planets in the Solar System. They are mostly made of gas and spacecraft are unable to land on them.

Rocky planets

Closest to the Sun are the four rocky planets – Mercury, Venus, Earth, and Mars. They all began their existence in the same way, but over time became very different worlds.

Dwarf planets

Dwarf planets, such as Pluto, also travel around the Sun. These worlds are smaller than the other planets. Scientists think there may be dozens of undiscovered dwarf planets hiding in the Solar System.

Super-sized

The Solar System is so big that if the Sun were the size of a basketball, the Earth would be the size of a sesame seed – and it would be located more than 25 m (80 ft) away!
