5 Giant Asteroids Could Hit Earth Before 2100!

[00:00:01]What if I told you that somewhere in the darkness of space there are giant rocks silently moving through the solar system and a few of them have a tiny chance of crossing paths with Earth before the end of this century. Not tomorrow, not next week, >> [music] >> but within the lifetime of people already alive today.

[00:00:22]And here's the terrifying part. We may not get a second chance >> [music] >> because unlike earthquakes, hurricanes, or volcanoes, an asteroid impact is one of the few natural disasters humanity might actually be able to stop, but only if we see it coming.

[00:00:39]Welcome to Infinite Science. Today, we're diving into the real science behind dangerous asteroids, the objects being watched by astronomers, and why planetary defense is no longer science fiction.

[00:00:53]>> [music] >> Because the question is not just could an asteroid hit Earth? The real question is, >> [music] >> would we be ready? Every night, while most of us sleep, telescopes around the world scan the sky. They are not looking for aliens. They are not looking for stars.

[00:01:10]They are searching for objects that could one day become a threat to Earth.

[00:01:14]These objects are called near-Earth asteroids. Most of them are harmless.

[00:01:19]Many are small. Some burn up in the atmosphere before ever reaching the ground.

[00:01:24]But others are different.

[00:01:26]>> [music] >> Some are hundreds of meters wide. Some are larger than skyscrapers. [music] And a few are big enough that if they hit Earth, they could destroy a city, >> [music] >> devastate a region, or change life on the planet. The scary thing is that space is enormous and asteroids are dark, fast, and difficult to track.

[00:01:47]>> [music] >> They don't glow like stars. They don't announce their arrival. They simply move, and sometimes they come close.

[00:01:55]Now, before we go any further, [music] let's be clear. Scientists are not saying a giant asteroid is definitely going to hit Earth this century.

[00:02:03]The chances are usually very small. But, in planetary defense, even a tiny probability matters when the consequences are enormous.

[00:02:12]>> [music] >> Imagine someone told you there was a 1 in 10,000 chance that a city could be destroyed. [music] Would you ignore it? Probably not. That is how scientists think about asteroid risk. They calculate the orbit. They measure the speed. They predict future paths.

[00:02:29]Then, they ask [music] one crucial question. Could this object and Earth arrive at the same place at the same time? Most of the time, the answer is no.

[00:02:39]>> [music] >> But, sometimes the answer is we need to keep watching. And that is where the story becomes fascinating. [music] There are several asteroids that have appeared on scientific risk lists over time.

[00:02:52]Their names are not always easy to remember.
