An asteroid that might be bigger than the Empire State Building is expected to fly past Earth over the weekend. 

Asteroid 2002 NN4, as NASA has labeled it, could be up to 18-hundred feet in diameter when it passes by on Saturday. 

New York City's iconic Empire State Building is more than 14-hundred feet tall.  Astronomers say the asteroid will pass Earth at a safe distance, despite its daunting size. 

Although, back in 2019 scientists from around the world gathered at a conference and discussed how to respond to an asteroid big enough to destroy a major city.
