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

Beyond the corona is the solar wind, which is actually an outward flow of coronal gas The sun’s magnetic fields rise through the convection zone and erupt through the photosphere into the chromosphere and corona The eruptions lead to solar activity, which includes such phenomena as sunspots, flares, prominences, and coronal mass ejections

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
