Study Notes
- Earth is in the Goldilocks zone, ideal for liquid water and supporting life due to factors like water, oxygen, and warmth.
- Conditions on other planets in our solar system are not suitable for human habitation.
- Exoplanets have not been found to be suitable for human life, and the distance to them poses a significant challenge.
- Planets like Gliese 667 Cc, Kepler-69c, Trappist-1e, Proxima Centauri b, and Kepler-452b show some similarities to Earth but are not yet proven to host life.
- Mars, despite being the most feasible option for colonization, presents challenges like extreme cold, toxic soil, lack of liquid water, low gravity, and dangerous radiation.
- Human survival on Mars would require advanced technology to create a habitable environment.
