What If Earth got Kicked Out of the Solar System? Rogue Earth

Summary by Krater

This video explains the gravitational dynamics of stars passing near our solar system, concluding that while close encounters are rare, a passing star could potentially eject Earth into deep space.

From the video

Answers: What would happen if a star passed close to our solar system?

• Gravity
• Stellar close encounters
• Oort cloud
• Gliese 710
• Earth extinction events

What it concludes

• A passing star could disrupt the Oort cloud, potentially sending asteroids toward the inner solar system.
• The star Gliese 710 is currently headed towards the solar system and will pass through the Oort cloud in about one million years.
• A close stellar flyby could eject Earth from the solar system, turning it into a rogue planet.
• Without sunlight, Earth's surface temperature would plummet to extreme cold, causing the collapse of the biosphere and human extinction.
