context_page_description: The Sun is the star in the center of our solar system. It is a yellow dwarf star. It gives off energy as light. That includes light, infra-red energy, ultraviolet light and radio waves. It also gives off a stream of particles, which reaches Earth as "solar wind". The source of all this energy is nuclear fusion. Nuclear fusion is the reaction in the star which turns hydrogen into helium and makes huge amounts of energy.
  The Sun is a star like many others in our Milky Way galaxy. It has existed for a little over 4.5 billion years. It is going to continue for at least as long. The Sun is about a hundred times as wide as the Earth. It has a mass of 1.9891×10³⁰ kg. This is 333,000 times the mass of the Earth. The Earth can fit inside the Sun 1.3 million times.
