- Sun - Wikipedia
The Sun is the star at the centre of the Solar System It is a massive, nearly perfect sphere of hot plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy from its surface mainly as visible light and infrared radiation with 10% at ultraviolet energies

Without the Sun’s energy, life as we know it could not exist on our home planet The temperature in the Sun's core is about 27 million degrees Fahrenheit (15 million degrees Celsius) – hot enough to sustain nuclear fusion This creates outward pressure that supports the star's gigantic mass, keeping it from collapsing

Our Sun is about 100 times wider than Earth, but it is just an average sized star Astronomers have found some stars that are 100 times bigger than the Sun and others that are 10 times smaller The Sun is also right in the middle of its lifecycle Right now, our Sun is in a stage called yellow dwarf It is about 4 5 billion years old
- Sun | Definition, Composition, Properties, Temperature, Facts . . .
Sun, star around which Earth and the other components of the solar system revolve It is the dominant body of the system, constituting more than 99 percent of its entire mass The Sun is the source of an enormous amount of energy, a portion of which provides Earth with the light and heat necessary to support life

Earth and all other objects in our solar system orbit around the Sun due to gravity – the Sun contains over 98% of all mass in the solar system and so exerts a strong gravitational pull Like other stars, the Sun is a dense ball of gas that creates energy through nuclear fusion reactions in the core, creating helium atoms from hydrogen atoms

There is a 10-kilometre difference between the Sun’s polar and equatorial diameter This means it is the closest thing to a perfect sphere that has been observed in nature The Sun will consume the Earth When the Sun has burned all its Hydrogen, it will continue to burn helium for 130 million more years
