The sun is a giant ball of hot, glowing

gas called plasma.

It is 150 million km from Earth.

The Sun is so big, that it can fit 1,000,000 Earths inside it!

Without the sun, life wouldn't exist.

The sun's gravitational pull is the force that keeps Earth and all of the other planets in orbit.

The Sun's life cycle with be completed in 10 billion years.

Since the Sun is 4.6 billion years old

now, the life cycle will be complete when its 14.6 billion years old.

The Sun is the most important thing in the solar system.

Earth will dry out and dissolve if we had no Sun.

Solar flares shoot particles, or small pieces of the Sun, into space. These particles reach Earth and upset radio signals. They also cause auroras.

Auroras are colorful lights that can be seen near the North and South Poles.
