Because it could, in potential, wipe out the entire world. The other thing is that it's not an impossible act. There are comets, meteors, asteroids, and even bigger things whirling around in outer space, and some of them do come by Earth. One even came and exploded in our atmosphere in 2013 and did some major damage to a forest in Russia, so yeah, it's something we need to pay attention to, and many people at NASA and beyond do just that. The real question here though about whether we could deter such a thing is size. Confused? Don't be, it's honestly really simple. You may not realize it, but comets and meteors and asteroids actually come to Earth quite often. Meteor showers are one example of this. So why don't we fear them? Well, they're not big enough to cause damage. And the definition of an asteroid is not a "massive rock that can wipe out the planet", because some asteroids are only 3 feet in diameter, which means they aren't that big. And even IF one that size did come to Earth, it wouldn't cause much damage depending on where it landed. Not to mention, ANY rock that comes to Earth has to deal with our natural defense system...the atmosphere. The Earth's atmosphere doesn't just keep the air of our world in, it helps keep things out via heat. So if something tries to enter or leave the atmosphere, they'll have to deal with extreme temperatures as they barrel through it. That's why space shuttles have heat shields to prevent the craft from breaking up in the atmosphere. As for meteors, as they come into the atmosphere, the heat of trying to get into the deeper parts of the atmosphere often makes them disintegrate, which makes them no threat to the Earth. Asteroid of a certain size will have to face that same thing. That being said, we've all heard about major asteroids lurking out there in space. Heck, between Jupiter and Saturn is a massive asteroid belt that is full of asteroids that could take us out. And the bigger the ones that come to the Earth, the bigger problem we'll be in. For if it's big enough, the atmosphere can't burn it all off, which is why meteorites are found on Earth sometimes. To potentially end the Earth though, we're talking one of continental size. Heck, even one the size of Texas could potentially wipe us out for good. Because of this fear of a giant asteroid, NASA keeps constant watch over what's coming into space. I'm sure you've seen articles on asteroids that may or may not reach the Earth by year 20XX, and those may or may not be accurate, it just depends. But should an asteroid of massive size get on a collision course with Earth, we're all in trouble for the most part. So, let's pretend an asteroid of massive size is on a collision course to Earth, and for one reason or another we can't stop it. What would happen then? What would happen to the planet? Well, as the science equation goes, Force = Mass * Acceleration. We know the mass would have to be huge to cause potential planetary destruction, and the speed it would be going at to both reach Earth and punch through the atmosphere would have to be significant enough. Heck, if it was going super slow, the sheer size of it would be enough to cause widespread destruction. The biggest problem though would be when it breaks through the atmosphere and touches down on the ground. The force of the impact would be almost unimaginable. Think about the Hiroshima or Nagasaki bombs, the ones that basically wiped the cities off of the face of Earth. Try and remember the fallout of that, and times that by about one hundred or maybe even a thousand depending on the size. That's about what I'm talking about here. Forget about just nuclear and fire damage, I'm talking the energy released from an irresistible force (the asteroid) meeting an immoveable object (the Earth), such a collision will literally vaporize just about anything in the immediate area. If you don't believe that, look up pictures of believed meteor craters. Notice how there's a big hole in the ground with no sign of what was there before? . There was a study done about what would happen if a 10 kilometer asteroid hit New York, just the immediate impact of the rock was estimated to end about 2.5 million people in just the first few seconds of the impact strike. 2.5 million. And that's not considering the collateral damage or the subsequent damage that the asteroid would bring. "Wait a minute!", you ask, "What about if a giant meteor hit the ocean? Would that save us?" #InsaneCuriosity#RecentSpaceDiscoveries
