Scientists take threats from asteroids seriously, with asteroid YR4 2024 initially having a 3.1% chance of colliding with Earth in 2032, now revised to 0.0017%. New data suggests it may impact the moon instead, potentially risking debris reaching Earth. In 2029, the larger asteroid 99942 Apophis will pass close to Earth, prompting the UN to declare that year as the international year of planetary defense. Historical events suggest asteroids can have catastrophic effects, but recent calculations show manageable risks with proactive efforts in place.
