The year 2020 is gone but the threat to life is not yet over. As we are just six days into 2021, the National Aeronautics and Space Administration (NASA) said that six asteroids are set to make a close approach to Earth on January 6. And the scary thing is, two asteroids are as big as the Eiffel Tower.
According to NASA, four if the asteroids are relatively small. However, the remaining two are bigger than the Eiffel Tower. The biggest one 2008 AF4 is nearly 500 metres in diameter. It is travelling at a speed of 39,654 kilometres per hour. it was to hit the Earth, it would create an impact of a nuclear bomb.
Luckily, the asteroid does not pose threat to Earth as it is over 15 million km away. As per Indian Standart Time (IST), it will go past Earth at 2:30 AM on January 7.
2021 AJ is the smallest asteroid to go past the planet. However, it is still fast enough to destroy an entire city if its path changes. The other asteroids that will go past the planet are 32-metre 2018 KP1, 2021 AU, 2021 AC and 2016 CO247.
None of these asteroids, according to NASA, pose an immediate threat to Earth. Only NEOs (Near-Earth Objects) post threat to Earth and that too also depends on their size and the celestial objects burn upon entering the atmosphere. They are being traced because they are either closer to Earth than 7.5 million kilometres or because they are bigger than 150 metres.
