The Sun or Sol, is the star at the centre of our solar system and is responsible for the Earth’s climate and weather. The Sun is an almost perfect sphere with a difference of just 10km in diameter between the poles and the equator. The average radius of the Sun is 695,508 km (109.2 x that of the Earth) of which 20–25% is the core.

- The Sun makes up 99.86% of the mass of the Solar System
- The Earth could fit inside the Sun approximately 1 million times
- At its core the Sun has a temperatures of 15 million °C
- It is composed of 92.1% Hydrogen and 7.8% Helium
- The Sun is 24,000 – 26,000 light-years from the galactic centre
