NASA is monitoring an asteroid that may be as large as the Empire State Building, expected to pass Earth on Saturday, June 6.

Asteroid 2002 NN4 is estimated to be 250–570 meters (820–1,870 feet) in diameter, according to NASA’s Jet Propulsion Laboratory (JPL). New York City’s iconic Empire State Building is more than 1,400 feet tall at its tip.

The asteroid may seem daunting, but it will pass Earth at a safe distance, a representative for JPL told CBS News.
