Can Humans Survive on Other Planets? – Explained by Neil deGrasse Tyson

Neil deGrasse Tyson emphasizes that:

1. Earth Is Perfect for Us
Tyson often says, "Earth is a paradise compared to any other planet." We evolved here, so no other place in the solar system is naturally suitable for human life.


2. Harsh Conditions Elsewhere
Other planets have extreme temperatures, no breathable air, harmful radiation, and intense pressure differences:

Mars is the most talked-about option. It’s cold, has a thin atmosphere (mostly CO₂), and no magnetic field to block solar radiation.

Venus is too hot (about 460°C) with crushing atmospheric pressure and toxic clouds.

Moon has no atmosphere and huge temperature swings.



3. Survival Needs Technology
Tyson stresses that humans could live on other planets only inside heavily protected environments—like domes, underground habitats, or space stations. But we can’t walk outside like we do on Earth.


4. Terraforming Is a Fantasy (for Now)
Changing a planet to make it Earth-like (called terraforming) is a popular science fiction idea, but Tyson points out it's far beyond our current technology.


5. Why Not Fix Earth Instead?
He strongly believes in protecting Earth first. He often asks, “If we can make Mars livable, why can’t we fix Earth first?”
