Understanding the Threats to Our Solar System

What is the primary concern if Neptune were to be affected by a cosmic event?

• It would cause a meteor shower on Mars.

• It would increase the sun's temperature.

• It could destabilize the orbits of other planets.

• It would cause a solar eclipse.

What is a 'Stellar Flyby'?

• A star passing close to our Solar System.

• An asteroid hitting a planet.

• A comet passing close to the sun.

• A planet moving out of its orbit.

Why is Neptune considered vulnerable in the Solar System?

• It is the closest planet to the sun.

• It has the most moons.

• It is the smallest planet.

• It is the furthest planet from the sun.

What did the University of Toronto scientists conclude about Neptune's orbit?

• It could become unstable with a small change.

• It requires a minor adjustment to remain stable.

• It is unaffected by other celestial bodies.

• It is perfectly stable.

What is the main challenge in predicting the path of astronomical objects?

• Interference from other galaxies

What is a potential solution for humanity to survive cosmic threats?

• Creating space stations in the outer Solar System.

• Colonizing the moon.

• Building underground cities on Earth.

• Moving to another galaxy.

What resources are suggested for constructing space stations in the outer Solar System?
