A Massive Asteroid Passed
By the Earth on Thursday. While it posed no threat, experts say it came close.
The Asteroid, Named 418135
Is estimated to be between 1,150 and 2,560 feet in diameter -- as wide as eight football fields.
At Its Closest Distance
The asteroid came within 2 million miles of Earth, which, according to NASA, is actually a concern.
Any Object That Comes Within
120 million miles of the Earth is considered a “near-Earth object”, or NEO, and any fast-moving object within 4.65 million miles is classified as potentially hazardous.
Asteroid skimmed past Earth at around 23,300 miles per hour.
