Seven asteroids are zooming past Earth this week — and one is the size of a skyscraper

A "potentially hazardous" asteroid zoomed past Earth on Tuesday — and it's not the only one. In total, seven asteroids are expected to pass by our planet by the end of the week. 

The largest of the asteroids, named 2021 KT1, is approximately 600 feet, about the size of the Seattle Space Needle and taller than the Washington Monument. However, scientists believe it could be as large as 1,049 feet, comparative in size to New York City's Chrysler Building. The asteroid is classified by NASA as a "potentially hazardous object" because it is a near-Earth object that is larger than 492 feet, and passed within 4.6 million miles of Earth. For reference, the average distance between Earth and the moon is about 239,000 miles.
