Asteroid 2024 YR4, a 220-foot (67m) 'city-killer', currently has a four per cent chance of hitting the moon on 22 December 2032. However, fresh observations could mean the odds of a collision rise to as high as 30 per cent. If the massive asteroid does hit the moon, it could carve out a 0.6-mile-wide crater and shower Earth with lunar shrapnel.

"Given how important it would be to make the right call... there's no legal framework or agreement on the decision making protocol for what the response would be?"

This is a remarkable opportunity," said Bobby Braun, who leads space exploration for the Johns Hopkins Applied Physics Laboratory, in an interview. "From a probability standpoint, there's not going to be another chance to study a killer asteroid like this for thousands of years.
