![The Sun does not have enough mass to explode as a supernova. Instead, when it runs out of hydrogen in the core in approximately 5 billion years, core hydrogen fusion will stop, and there will be nothing to prevent the core from contracting. The release of gravitational potential energy will make the Sun more luminous and end its main sequence phase, leading the Sun to expand over the next 2 billion years: first into a subgiant for a billion years, and then into a red giant.[156][159][160] The heating due to gravitational contraction will further the Sun's expansion and lead to hydrogen fusion in a shell just outside its core, where unfused hydrogen remains, contributing to the increased luminosity, which will eventually reach more than 1,000 times its present value.[156] When the Sun enters its red-giant branch (RGB) phase, it will engulf (and destroy) Mercury and Venus. According to a 2008 article, Earth's orbit will have initially expanded to at most 1.5 au (220 million km; 140 million mi) because of the Sun's loss of mass. However, Earth's orbit will then start shrinking by tidal forces (and, eventually, by drag from the Sun's lower chromosphere) so that it is engulfed by the Sun during the tip of the red-giant branch phase 7.59 billion years from now, 3.8 and 1 million years after Mercury and Venus have respectively suffered the same fate. #sun #space #fyp #earth #redgigant](/video/cover/7654617268592053527.webp)
