Famed astrophysicist Neil deGrasse Tyson has issued a grave warning about a 'city-killer' asteroid whose odds of smashing into Earth recently doubled.
Neil deGrasse Tyson has warned about asteroid 2024 YR4, which now has a 2.3% chance of hitting Earth in 2032, up from 1.2%. The asteroid, measuring 130 to 300 feet in diameter, could cause a 7.7-megaton blast. NASA is monitoring it with the James Webb Space Telescope, and a mission similar to the successful DART (Double Asteroid Redirection Test) could be launched to deflect it if necessary.
