We are so amazed by how gigantic the Sun is, and we may wonder what is inside this big ball of energy in our solar system. What is it that makes the Sun the powerhouse of our solar system and the source of almost all of the Earth’s various forms of energy? What is the Sun made of that releases heat to keep us going?

The solar system is named after the Sun- solar means “the Sun”. The Sun holds all the members of the system together. It keeps the family together, so to speak, through its gravitational pull. This gravitational pull is 28 times the gravitational pull on the surface of the Earth.

The Sun is a star. Like all other star, it is composed of burning gases such as hydrogen and helium. Gravity then pulls together the burning gases of the Sun and stars. Large amounts of energy are produced by the Sun and the stars mainly due to the burning gases inside them.

This energy is released in outer space as heat and light which provide the living things and the whole solar system the heat it needed. Aside from hydrogen and helium, it is also composed of carbon, nitrogen, oxygen, magnesium, sulfur, silicon, and iron. Nuclear reactions at the core of the Sun change hydrogen into helium and then generate massive heat.

A star has a very different composition when compared to the Earth. Unlike the Earth, the Sun (just like any star) has no plants and no life. Ever wonder how long will the Sun release those vast amounts heat and light energy? Will this turn in an end in the years to go?

Don’t worry. Scientists researched the capabilities of the Sun and have found out that it would still be able to produce energy for 10 more billion years!
