It is 4.5 billion years old, which is thought to be its mid age. This means it shall keep shining for about five billion more years to come.
The sun's surface is known as the photosphere. Its temperature is about 5,778 K. The sun's core is, however, much hotter, with its temperature being about 15.7 million K. All this energy is produced via nuclear fusion. This is a nuclear reaction where two hydrogen nuclei fuse to form one helium nucleus, accompanied by release of energy.
The separation from the Earth to the sun is 149.6 million kilometers. The distance across of the sun is 1.392 million kilometers. It has a tropical periphery of 4.379 million kilometers.

It has a volume 1.3 million times that of earth.
The energy from the sun is called solar energy. It is received by the earth through radiation. Since only a fraction of the radiated energy can be absorbed by our planet, a lot of it is reflected back to space. Life on earth depends on the absorbed energy. It is also responsible for our weather, tides and the water cycle.
