A massive asteroid could hit Earth in 2032, warns the US space administration Nasa, which estimates there is a 3.1 percent risk of a direct hit.
Although it may seem that the risk is relatively small, and the danger also lies far in the future, Nasa emphasizes that asteroid 2024 YR4 is the greatest threat from space in modern times.
The threat from 2024 YR4 may seem frightening to some as the asteroid is large enough to flatten an entire city, but experts see no reason to sound the alarm.
‘I’m not panicking, says researcher Bruce Betts at the Planetary Society’.
