What is the Sun?

Protected question
The Sun is a star. The Sun is a yellow dwarf, one of the most common types of stars. It is 5000o C at the surface, but he inside is about 15,000,000 degrees. The Sun was formed when a cloud of dust and gas released from a supernova began to clump in the middle. It clumped so hard that the friction from the clumping began to generate enough heat for the fusion of hydrogen to occur. Energy in the sun is produced by nuclear fusion.

Fusion is the process of joining two nuclei together which, in the sun's place, is hydrogen nuclei, thus creating intense heat that turns the hydrogen gas to plasma, a state of matter where electrons are ripped off atoms. The hydrogen is the "fuel" of the sun, and if the sun runs out of hydrogen it will die in an explosive process known as a fusion flash. The waste product of the of hydrogen nuclei is helium, and it's building up in the sun until it dies. The leftover cloud of dust and gas began to form planets.

At first, there were planetesimals. Then they joined together to form planets. The Asteroid Belt was formed because gravity from Jupiter prevented them from clumping together. The Sun almost became a binary star system with Jupiter, but Jupiter was a little too small to become a star. The Sun is now 50/50 in proportion to the hydrogen and helium, and is now about 4 billion years old. It will live for another 4 billion years.
