NASA has sent out probes to destroy some of the objects that are moving towards our atmosphere to prevent anything hitting Earth. NASA says that there are no asteroids currently on the course to hit Earth anytime soon and are on alert identifying asteroids. Millions of years ago, a giant asteroid hit the Earth, causing the extinction of Dinosaurs. Today, more asteroids are being found that could hit the Earth and such and alarming speed that it might wipe out everything on Earth. Scientist are doing the best that they can to send probes to these asteroids to destroy them, before they come into the Earth’s atmosphere. The problem is that there is so much stuff that is in our solar system that it is hard for them to find the asteroids that are a potential threat to Earth. Scientist say that an asteroid will hit our Earth eventually and will wipe out everything on Earth, but they do not know when that will happen. If an asteroid did hit Earth, it would send out large clouds of dust that will go up onto the atmosphere and block out the sun. the Earth will become colder and will force us into an ice age.
