NASA has warned of a potentially hazardous asteroid will zoom past Earth at over 20,000 MPH later this week.
, which NASA keeps updated. Based on observations, the asteroid is between 42 to 92 feet in diameter. It will zoom past the Earth at more than 20,000 mph, but it won’t pose any threat to our planet.An illustration of asteroids approaching Earth. Image source: auntspray / Adobe
Astronomers named the asteroid in question 2015 FF. At its closest approach, the asteroid will travel at around 27 times the speed of sound,notes. Additionally, it will come within around 2.67 million miles of the Earth. That’s roughly eight times the average distance between Earth and its Moon. It won’t pose a direct threat to Earth, but such an approach by a potentially hazardous asteroid is concerning.
Just because the asteroid isn’t aimed at Earth doesn’t make it any less dangerous. And any asteroid labeled as “potentially hazardous” isn’t necessarily a danger to Earth. NASA just labels any celestial object that comes within 120 million miles of Earth as a near-Earth object. Additionally, any object that comes within 4.65 million miles is considered potentially hazardous. That’s where 2015 FF lands.
The asteroid itself doesn’t pose a threat to Earth at the moment. But, a potentially hazardous asteroid of the same size, with a route that takes it into a direct impact with Earth could pose a lot of danger to cities. Currently, NASA knows the orbit of around 28,000 asteroids. It keeps track of all of these asteroids so that astronomers can watch them as they pass and for any signs of danger.2015 FF might not pose a direct threat, but there may one day be an asteroid that does.
