587 - How can we protect Earth from asteroids or comets that might collide with it?

To protect Earth from asteroids or comets, scientists suggest these steps:

  1. Detection: Find asteroids and comets early using big telescopes.
  2. Tracking: Follow their paths to see if they might hit Earth.
  3. Deflection: Push or pull the asteroid off course using:
    • Kinetic impactors (spacecraft that crash into the asteroid)
    • Gravity tractors (spacecraft that pull the asteroid with gravity)
    • Solar sails (using the sun's energy to push the asteroid)
  4. Disruption: Break the asteroid into smaller pieces that will burn up in Earth's atmosphere or miss the planet.
  5. Impact mitigation: Prepare for an impact by having emergency plans, evacuation routes, and shelters.

It's a big job, but scientists and governments are working together to protect our planet from asteroid and comet threats.
