What if an Asteroid Struck the Earth?

By Aazam

Our planet being struck by an asteroid is the stuff of science fiction. This concept is the subject of numerous films and books, or attempts to stop one

Asteroid impacts on Earth aren't just the stuff of science fiction; they do happen on occasion

The sole objective of the "asteroid watch" at NASA's Jet Propulsion Laboratory in California is to find and monitor asteroids that the organisation believes will pass relatively near to Earth

At least five are listed on the Asteroid Watch dashboard for 2022 alone, with one estimated to be nearly 2.5 times as tall as the Empire State Building in New York City

This asteroid (7482) bears the designation 1994 PC1 and has been recognised by NASA since that year

On January 5, 2022, two of the five asteroids—2021 YQ and 2021 YX—safely passed by Earth at distances of 1.3 and 2.4 million miles, respectively

The Moon and Earth both have obvious craters that attest to the planet's lengthy history of being struck by large objects

The asteroid that struck Earth 66 million years ago is the most well-known one to have ever been found

The Double Asteroid Redirection Test (DART) robotic spacecraft, which NASA sent into space in November 2021, is the good news

Its sole objective is to collide with the tiny asteroid Dimorphous at a speed of 4.1 miles per second in an effort to significantly alter its orbit
