What If The Sun Exploded? | COLOSSAL QUESTIONS
Colossal Cranium・2 minutes read
A supernova is a powerful event caused by a star exploding, with temperatures 15 times hotter than the sun's surface. Our sun, though too small to become a supernova, will eventually expand into a red giant, engulfing inner planets before turning into a dense white dwarf in the distant future.
Insights
- Our sun, despite being incapable of becoming a supernova due to its size, will undergo a transformation into a red giant and then a white dwarf, leading to the destruction of inner planets like Mercury, Venus, and Earth, with Mars left as a scorching desert.
- This transformation process, expected to take place in several trillion years, provides humanity with a significant timeframe to anticipate and prepare for the sun's destructive effects on the solar system, ensuring that there is ample time to develop strategies to mitigate potential consequences.

Recent questions
What is a supernova?
A supernova is a rare and powerful event that occurs when a star explodes, vaporizing everything in its path with extreme temperatures.
Can our sun become a supernova?
Our sun, being medium-sized, is too small to explode into a supernova. Instead, it will eventually turn into a red giant and then a white dwarf.
What happens when a star becomes a red giant?
When a star becomes a red giant, it expands to engulf inner planets like Mercury, Venus, and Earth, leaving Mars as a scorching desert.
What is a white dwarf?
A white dwarf is the dense remnant of a star after it sheds its outer layers, much denser than Earth.
How long until our sun transforms into a red giant?
The transformation of our sun into a red giant and then a white dwarf is expected to occur several trillion years in the future, giving us ample time to prepare for its effects.

Sun's Future: Red Giant to White Dwarf
- A supernova is a rare and powerful event that occurs when a star explodes, vaporizing everything in its path with extreme temperatures. If our sun were to explode into a supernova, the entire solar system would be destroyed, with temperatures 15 times hotter than the sun's surface.
- Fortunately, our sun, being medium-sized, is too small to explode into a supernova. Instead, it will eventually turn into a red giant, expanding to engulf Mercury, Venus, and Earth, leaving Mars as a scorching desert. The sun will then shed its outer layers, becoming a white dwarf, much denser than Earth.
- While our sun won't become a supernova, its eventual transformation into a red giant and then a white dwarf will still have destructive consequences for the inner planets. However, this process is expected to occur several trillion years in the future, giving us ample time to prepare for its effects.
