Our sun is a star. Like all stars,it is a mass of(~"大团)very hot gases. The sun，s energy doesn't come from burning fuels(燃料).

The sun's energy comes from its nuclear fusion(核聚变）.How big is the sun? Its diameter，the distance across its center, is quiet huge. That's more than one hundred times the diameter of

Earth. The sun's volume is more than a million times the volume of Earth. Another way to say this is that the sun could hold one million Earths inside(在.. 内)it.

The sun has different layers(层)of gases. Each layer mixes into the next，like the layers of Earth's atmosphere(大气).Most of the sun's mass is in its center. It is also very hot. Almost all fusion takes place in the center.

The sun creates energy in the form of heat and light. Even though the sun is a ball of gases, it is made up of several layers. The main layers are the center. There are also other layers. The sun produces huge energy. Its energy mainly comes from its center. The sun is the source of most of the energy on Earth. Without the sun,there will be no living things on earth,including human beings.
