Our Sun
Our Sun is a common middle-sized star which scientists have named Sol after the ancient Roman name. This is also why our system of planets is called the solar system. There are trillions of stars in the universe just like the Sun. Numerous stars that are like the sun have their own system of planets, comets, moons and asteroids.
The Sun was born in a massive cloud of gas and dust around 5 billion years ago. Over a period of millions of years this gas and dust began to fall into a common centre under the force of its own gravity.
At the centre, an increasing body of mass was forming. As the matter fell inward, it produced a great amount of heat and pressure. As it grew, the Sun became hotter and hotter. Eventually, when it reached a temperature of around 1 million degrees, its core exploded, Triggering it to begin nuclear fusion. When this happened, the Sun began producing its own light, heat, and energy.
