Sun


The sun's Diameter is 1392000km. 109 Earth's can fit across it. The Romans Called it sol, which in English means sun. In ancient Greece, the sun was called Heloies. Our sun is not unique in the universe. It is a common Middle aged star which scientists have named Sol after the ancient Roman name. This is why our system is called the solar system. There are trillions of other stars in the universe just like it. Many of these stars have their own systems, their own planets, moons, asteroids and comets. The sun was born in a vast cloud of gas and dust around 5 billion years ago. These vast nebulae are the birth places of all stars. Over a period of many million of years, this gas and dust began to fall into a common centre under the force of it's own gravity.
