00:00What if a space rock the size of a football field was heading toward Earth?
00:03Right now. These are called city-killing asteroids, powerful enough to destroy an
00:08entire metropolitan area. If one hit a major city, the explosion could release energy equal
00:13to multiple nuclear bombs. Buildings flattened. Fires spreading. Shockwaves felt miles away.
00:23But here's the good news. Space agencies around the world are watching the skies.
00:30Advanced telescopes track thousands of near-Earth objects every year calculating their paths
00:35to predict potential danger. In fact, scientists have already tested technology to change an
00:40asteroid's direction, proving planetary defense is possible. So while the threat is real,
00:45humanity is not defenseless. Would we survive a city-killing asteroid? Comment your thoughts below.
