A large asteroid is expected to pass within 4.5 million miles of the Earth on Tuesday — a measure that’s nearer than 20 times the distance between here and the moon.
The asteroid, called 2021 KT1, measures about 600 feet, which is about the size of the Seattle Space Needle, according to NASA’s Jet Propulsion Laboratory.
The asteroid is classified by NASA as a “potentially hazardous object” because it’s larger than 492 feet and is expected to pass within 4.6 million miles of Earth.
