The Sun would have been surrounded by a disk of gas and dust early in its history when the solar system was first forming 4. Some of that dust is still around today, in several dust rings that circle the Sun. They trace the orbits of planets, whose gravity tugs dust into place around the Sun.

The temperature in the Sun's core is about 27 million degrees Fahrenheit 15 million degrees Celsius — hot enough to sustain nuclear fusion. This creates outward pressure that supports the star's gigantic mass, keeping it from collapsing.

The Sun has inspired us since ancient times. Countless musicians have written songs about the Sun. If you're Superman or a fellow Kryptonian, your powers are heightened by the yellow glow of our Sun, and you can even dispose of dangerous materials, as Superman and Superboy did, by hurling them into the Sun.

Astronauts are supposed to use a bomb to divert the flare. To save humanity, astronauts try to reignite the Sun with a bomb, though things don't quite go as planned.

Instead, people build giant rocket thrusters to move the Earth to a new star system. The Sun is a star. It is the center of our solar system. The Sun is a hot ball of glowing gases. It keeps our planet warm enough for living things to grow.
