Nasa has upgraded the risk of a potential “city-killer” asteroid colliding with the Earth to 3.1 per cent — the highest level calculated for a collision.
Scientists have warned that a direct hit, which could occur on December 22, 2032, has the potential to release nearly 8 megatons of energy — enough to devastate a city, with the blast radius of about 30 miles.
The object, called 2024 YR4, is estimated to be about 40 to 90 metres wide and is hurtling through space at about 38,000mph. The impact would occur somewhere along a path that extends across the eastern Pacific Ocean, northern South America, the Atlantic Ocean, Africa, the Arabian Sea and southern Asia.
Just nudge it to Toronto.
