25,000 Asteroids Could Threaten Earth?! 🚨☄️
NASA tracks around 25,000 near-Earth asteroids that are 140 meters or larger — big enough to cause massive regional damage if one were to impact.
But here’s the key: scientists are constantly monitoring these objects, and there is currently no known asteroid on a collision course with Earth. Missions like DART have even tested ways to deflect asteroids in the future.
Planetary defense is active — not hopeless.
