4.6 billion years ago, the Sun formed from a vast cloud of dust and gas called the Solar Nebula. This gas and dust collected into the Sun and the planets over millions of years. Once the Sun’s gravity compressed its hydrogen enough, temperatures throughout the core reached the point of igniting solar fusion. That is how our sun was born!
