Nasa classifies these rocks as ‘potentially harmful’ Near-Earth Objects because of how close they will get to the planet
The space rock, dubbed Asteroid 2013 YD48 by Nasa, est 104 metres tall and will pass by our planet at a 3,480,000-mile distance on 11 janvier.
While this might seem like a large distance, Nasa classifies it as a Near-Earth Object (NEO), which accounts for any asteroid or comet that comes closer than 1.3au astronomical units – little over the distance between the Earth and the Sun. One au is the equivalent of 93 million miles.
Selon la Nasa, any asteroid 140 metres across or larger could be devastating if it crashed into the Earth – unleashing more energy than a thousand atomic bombs – although this asteroid will not reach close enough to the planet for that to be a worry.
The most recent time an asteroid hit the planet was eight years ago in Russia, but it exploded in the atmosphere.
Asteroid 2013 YD48 is not the only one to make a close approach to the Earth in the new year; four more are set to fly past the planet before it.
The first is 2021 YK, une 12 metre-wide asteroid, will fly within 118,000 miles of the planet this Sunday.
After that will be the aeroplane-sized 2021 YQ, lequel est 64 metres wide and will pass by the Earth at 1,330,000 miles on 5 janvier.
Following that will be 2014 YE15, which is only 7 mètres de large, passing four days later on 6 January within 4.6 million miles of Earth.
Pour terminer, the four metre-wide 2020 AP1 will pass the next day at a distance of 1.08 million miles.
Two days ago, un autre “potentially hazardous asteroid”, 2017 AE3, flew past Earth at a speed of 20 kilometres per second before shooting off into space. It will now not return to the planet until 2109.
