The Sun and Nuclear Fusion

The Sun is by far the biggest object in the Solar System.

In the picture, the planets at the right are shown to scale. The Earth is the first planet in the third row.

The Sun makes energy by a process called nuclear fusion.

Hydrogen atoms in the centre are under great pressure and temperature.

When they combine to make helium they release energy.
