Five smaller asteroids heading towards Earth pose significant threat

The video discusses the potential threat of small asteroids colliding with Earth over the next century. Chinese astronomers have identified five asteroids with a significant collision risk. Despite their small size, these asteroids can cause massive damage due to their kinetic energy, as demonstrated by the 2013 Chelyabinsk event. Tracking these asteroids is challenging due to their size and number, with estimates ranging from 100,000 to 1,000,000. The video emphasizes the importance of monitoring these space rocks to prevent potential disasters.
