‘City killer’ asteroid just missed Earth after it ‘snuck up’ on us, experts say
The Earth had a surprise visitor Thursday, and not a welcome one. An asteroid big enough to earn the nickname "city-killer" from astronomers whizzed by at a close distance, and it wasn't detected soon enough to take any defensive action had that been necessary, reports the Washington Post. Another outlet, CNET, likens the pass-by of Asteroid 2019 OK to having a "baseball [whistle] by your ear" as you walk down the street. The asteroid is about 330 feet wide and came within about 45,000 miles of Earth, one fifth the distance to the moon.
