Exploring Earth 2.0: The Quest for a New Home

What are some potential threats to Earth's long-term habitability?

• Deforestation

• Giant meteorite impacts

• Nuclear war

• Overpopulation

Why is it important for humanity to consider colonizing other planets?

• To escape from pollution

• To ensure survival in case of Earth's destruction

• To explore new cultures

• To find new resources

What is an exoplanet?

• A planet within our solar system

• A planet orbiting a star outside our solar system

• A dwarf planet

• A planet that has no atmosphere

What makes Proxima B a significant discovery?

• It has the most moons

• It is the hottest exoplanet

• It is the largest exoplanet found

• It is the closest exoplanet to Earth

What is the Goldilocks region?

• A region with the most stars

• A region with the least gravity

• A region where a planet is not too hot or too cold for liquid water

• A region with abundant gold

How does Proxima B's orbit compare to Earth's?

• Proxima B has the same orbit as Earth

• Proxima B orbits much closer to its star

• Proxima B orbits much farther from its star

• Proxima B orbits in the opposite direction

What is a Mega Flare?

• A small solar flare

• A powerful burst of radiation from a star

• A type of comet

• A large asteroid

How do Mega Flares affect Proxima B?

• They increase the planet's temperature

• They strip away the planet's atmosphere

• They stabilize the planet's orbit

• They create new water sources

Why might Proxima B not be a viable Earth 2.0?

• It lacks an atmosphere due to Mega Flares

• It is too far from Earth

• It is too small

• It has too many moons

What is the main challenge of finding a new habitable planet?

• Finding a planet with the same gravity as Earth

• Finding a planet with abundant resources

• Finding a planet in the habitable zone with a stable atmosphere

• Finding a planet with the same size as Earth
