An asteroid that’s twice as big as London’s iconic Big Ben is set to zip past our planet today, according to NASA, Eurasia Diary reports citing Mirror.

The asteroid, dubbed 2009 BH2, will make a close approach with Earth at around 14:29 GMT.

The space rock is estimated to be around 88 metres - 200 metres in diameter. At the higher end of that estimate, it suggests the asteroid could be twice the size of Big Ben!

During today’s passing, the asteroid will be around 2.8 million miles away from our planet. While this might sound far, it’s considered a ‘close approach by NASA.’

2009 BH2 won’t be the only asteroid to pass our planet today - a second smaller space rock will pass Earth today at around 12:30 GMT.

This asteroid, called 2020 AH1, is significantly smaller, with an estimated diameter of 33 metres - 75 metres.

Thankfully, the chances of either asteroid colliding with our planet are extremely low.

However, NASA hasn’t written off the chances of an asteroid collision in the near future.

NASA discovers around 30 new ‘near-Earth objects’ (NEOs) every week, and at the start of 2019 had discovered a total of more than 19,000 objects.
