What If Another Planet Entered Our Solar System?

What if a rogue planet suddenly drifted into our solar system? Could it knock Earth out of orbit? Would it collide with other planets or send asteroids flying toward us? In this video, we explore how an intruding planet could destabilize everything — from our orbits to the asteroid belt — and what it would mean for life on Earth. This cosmic "what if" might sound like science fiction, but rogue planets are real... and they're out there.
