Editing Sun (section)

==Significance==

The Sun is the main source of energy for the Earth. This energy is made deep inside the Sun in a process called [[nuclear fusion]]. Four hydrogen atoms are fused together to make one [[helium]] atom. Some of the leftover matter turns into energy. This is the same way energy is released in a hydrogen bomb.{{cn|date=March 2025}}

It can take between 10,000 and 170,000 years for the [[energy]] in the core of the Sun to escape. The Sun is the most important source of [[energy]] for [[life]] on [[Earth]]. Without the Sun, there would be no [[vegetation]] on [[Earth]]: every [[plant]] needs light to live and grow. Everything on Earth would freeze over without the Sun. The Sun gives the Earth heat as well as light. Plants make oxygen by [[photosynthesis]]. All [[Human|humans]] and [[Animal|animals]] breathe oxygen. The [[Earth]]'s position in the Solar System is just right for the development of life on Earth.{{cn|date=March 2025}}
