Interesting facts about the SunSun Facts for Kids

Enjoy these fun Sun facts for kids. Learn how hot the Sun is, how long it takes light from the Sun to reach Earth, what the Sun is made of and more.

Read on for a range of interesting facts about the Sun.

 


  • The Sun is a star found at the center of the Solar System.

  • It makes up around 99.86% of the Solar System’s mass.

  • At around 1,392,000 kilometres (865,000 miles) wide, the Sun’s diameter is about 110 times wider than Earth’s.

  • Around 74% of the Sun’s mass is made up of hydrogen. Helium makes up around 24% while heavier elements such as oxygen, carbon, iron and neon make up the remaining percentage.

  • Light from the Sun reaches Earth in around 8 minutes.

  • The Sun’s surface temperature is around 5500 degrees Celsius (9941 degrees Fahrenheit), so pack plenty of sunscreen if you plan on visiting (remembering that the average distance from the Sun to the Earth is around 150 million kilometers).

  • The Sun’s core is around 13600000 degrees Celsius!

  • The Sun generates huge amounts of energy by combining hydrogen nuclei into helium. This process is called nuclear fusion.

  • Because of the Sun’s huge influence on Earth, many early cultures saw the Sun as a deity or god. For example, Ancient Egyptians had a sun god called Ra while in Aztec mythology there is a sun god named Tonatiuh.

  • The Sun produces a solar wind which contains charged particles such as electrons and protons. They escape the Sun’s intense gravity because of their high kinetic energy and the high temperature of the Sun’s corona (a type of plasma atmosphere that extends into space).

  • Planets with strong magnetic fields such as Earth manage to deflect most of these charged particles as they approach.

  • A solar eclipse occurs when the Moon is between the Sun and the Earth.
