Space is full of objects like asteroids, comets, stars, planets, meteors, stars, galaxies and more. There are instances when due to the gravitational pull Earth tends to attract certain objects like asteroids and meteors and they do crash onto Earth. However, there is no potential harm caused by these objects until and unless they are large such as the asteroid that killed off all the dinosaurs. Needless to say, Earth needs a defense system in place in order to prevent any kind of mishap. NASA had revealed that the dinosaurs went extinct 65 million years ago as a result of a single asteroid strike or comet impact on Earth, but also shared another possibility.
"Extinction of the dinosaurs may have occurred 65 million years ago as a result of single asteroid or comet impact, but it is also possible they died out as a result of many comet impacts over one to three million years, group of scientists has theorized. Comet showers occurring over period of time may have caused the extinctions, said Dr. Paul Weissman of NASA's Jet Propulsion Laboratory in Pasadena, Calif., one of eight authors of paper recently published in Nature, the British scientific journal," NASA said in a report.

Therefore, staying alert and prepared is important as any similar strike will destroy Earth in unfathomable ways and may even lead to extinction of humans. Yes, the potential for horror is massive.
With this aim, NASA launched the Double Asteroid Redirection Test (DART) mission in November 2021. DART is the world’s first planetary defense test mission dedicated to investigating and demonstrating one method of asteroid deflection by changing an asteroid’s motion in space through kinetic
