Sun Facts The Sun is the star at the centre of our solar system. It is an almost perfect sphere of super-hot gases whose gravity holds the solar system together. The energy produced by the Sun is essential for life on Earth and is a driving force behind the Earth’s weather. Facts ab...
NASA explains, The solar wind is created by the outward expansion of plasma (a collection of charged particles) from the Sun. This plasma is continually heated to the point that the Sun’s gravity can’t hold it down. It then travels along the Sun’s magnetic field lines that extend radi...
