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.
