What happens when Earth gets no second chance? This video explores how to stop an asteroid, highlighting NASA's successful double asteroid redirect test (DART) mission. We examine the critical role of planetary science in understanding and mitigating cosmic threats, alongside strategies like multiple kinetic impactors and nuclear devices for scenarios like 2024 PDC-25. The DART mission, which successfully altered dimorphos orbit, validates kinetic impactors as primary asteroid deflection tools,

Asteroid 2024 YR4: What’s Really Happening? 🚀 👉Asteroid 2024 YR4 is a ~60-meter near-Earth space rock discovered in late 2024 that briefly raised impact concerns. Continued tracking with telescopes and NASA’s James Webb Space Telescope refined its orbit and showed it no longer poses a threat to Earth in 2032. However, updated calculations now give it a small ~4% chance of hitting the Moon on December 22, 2032, meaning there’s about a 96% chance it won’t. Scientists are studying ways to deflect
