11 Questions
Why is Earth in the Goldilocks zone?
Because it is at just the right distance from the Sun for liquid water to exist
What role does Earth's atmosphere play in maintaining favorable temperatures?
Capturing warmth and ensuring favorable temperatures
How does Earth's magnetic field benefit life on the planet?
It helps shield against harmful solar radiation
What is the significance of water on Earth according to the text?
Water was necessary to start life on Earth billions of years ago
Why doesn't Earth get excessively hot despite its proximity to the Sun?
The atmosphere captures warmth while shielding from excessive heat
What would happen if Earth were too close to the Sun?
Temperatures would be too high for life to exist
What is the primary reason Earth is considered the perfect home for life?
It has the necessary factors for life, including water, oxygen, and warmth.
According to the passage, what is the main challenge in finding a new home planet for humans outside of Earth?

Kepler-452b is too far away, being about 1,800 light years from Earth.
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.
Explore the concept of leaving Earth and colonizing a new planet as a potential solution in case of environmental disasters or climate change. Is human settlement on other planets a sustainable option for the future?
