The Sun lies at the center of a great collection of circling bodies that we call the Solar System . They were all born together nearly 5,000 million years ago out of a vast cloud of gas and dust that once existed in our part of space. The Sun is quite different from the other bodies in the Solar System. They are made up of rock, ice or cold gas,but the Sun is a globe of searing hot gases. If we could travel to the stars, we would find that they look like the Sun. We can think of the Sun as our daytime star .
