"The Gruesome Fate of Planets When the Sun Dies: A Terrifying Revelation"

In about 5 billion years, the Sun will transform into a red giant, expanding and ultimately leading to the destruction of the solar system. The inner planets, including Mercury and Venus, will be swallowed by the Sun's expansion, while Earth's fate is uncertain. The outer planets will also be affected, with the possibility of Saturn's moon Titan becoming temperate. Eventually, the Sun will expel its outer layers, leaving behind a planetary nebula and removing the outermost planets from its orbit.
