A large, harmless asteroid will zip past Earth this weekend

A large asteroid will zip past Earth this weekend, but don't worry: It poses no danger.The space rock — 1997 NC1 — makes its closest approach Saturday morning, coming within 1.6 million miles (2.

6 million kilometers), according to the European Space Agency.Discovered nearly three decades ago by an asteroid-tracking system in Hawaii, the asteroid is between 2,461 feet (0.75 kilometer) to 5,413 feet (1.

65 kilometers) wide — roughly the size of two to four Empire State Buildings.Skygazers with binoculars and small telescopes may be able to spot the asteroid as a small point of light passing harmlessly through the sky. It won't greet Earth from such a distance again until 2133, according to NASA.

The last time an asteroid similar in size passed safely by Earth from an even closer distance was in 2022, when a space rock called 1994 PC1 made its approach.NASA, ESA and other space agencies track the paths of asteroids and other space junk so they can keep Earth safe from any possible collisions. Last year, astronomers tracked a smaller asteroid resembling a spinning hockey puck and said there's no chance of it hitting Earth or the moon.
