In the distant future, the Sun, the center of our solar system and the source of life on Earth, will meet its inevitable demise. As a star classified as a "yellow dwarf," the Sun will exhaust its nuclear fuel, hydrogen, over billions of years. This process triggers a series of transformations known as the "red giant phase," where the Sun expands, engulfing Mercury and Venus, and causing Earth's atmosphere to evaporate. Subsequently, the Sun will shed its outer layers, forming a planetary nebula, and leaving behind a dense core known as a "white dwarf." This celestial metamorphosis marks the end of the Sun's life cycle, leaving behind a remnant that slowly cools and fades into oblivion.
