📖 Chapter 2 of 6 · How the Sun Says Goodbye · All ages
The Sun swells into a red giant
The Sun will balloon out hundreds of times bigger than it is now. It grows so huge that it swallows Mercury, Venus, and almost certainly Earth and the Moon too — they'll simply be inside the Sun's outer edge.
Mars sits right near the new edge, so scientists aren't sure if it survives or not.
No explosion happens here — just slow, gentle swelling.
