What is the Solar System?

A solar system is made up of one or more stars and every object that orbits around it/them. A solar system that has 2 stars is called a binary star system. A solar system that has 3 or more stars is called multi-star system. Solar systems are made up of planets, their moons, dwarf planets, comets, asteroids and other smaller objects. Our Solar System is in the Milky Way Galaxy and our solar system’s only star is called The Sun. There are 8 planets that orbit around The Sun (there may be more we have not found yet), the 8 planets in our solar system that we have found, in order of distance from the sun are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune

The Solar System was created 4.6 billion years ago when a large cloud of spinning gas and dust in space collapsed. Hydrogen and helium started to collect at the center of the swirling mass, this ball of material that collected at the centre of the spinning cloud is known as a protostar. Over 50 million years the pressure and temperature inside this ball increased, as they did, hydrogen atoms began to join together to make helium, releasing huge amounts of energy.

This is how our Sun was born and this "fusion" of hydrogen atoms is what powers The Sun. Most of the material in the cloud was eventually swallowed up by The Sun. The rest of the material orbiting around the centre came together to make smaller objects, the objects that were large enough to became spheres due to their gravity became planets. The smaller objects became asteroids, comets and meteoroid.
