Nasa upgrades chances of asteroid 2024 YR4 hitting Earth in disaster event
Astronomers are considering a mission to blow up the asteroid 2024 YR4 to prevent potential damage to Earth-orbiting satellites.
The 65-metre near-Earth space rock has a 4 per cent chance of impacting the Moon in December 2032, potentially creating a 1km crater.
A lunar impact could generate a massive debris cloud, exposing Earth's satellites to meteorites for years.
Scientists, including those from Nasa, propose a 'kinetic disruption mission' involving breaking the asteroid apart, with nuclear explosive devices being seriously considered.
The proposed mission could involve two 100-kiloton nuclear devices and would require five to seven years of development, with a launch window between late 2029 and late 2031.
