A quiet neighbour of the Milky Way, the Small Magellanic Cloud (SMC), appears to be falling apart. And scientists say they didn’t see it coming.

'City-killer' asteroid 2024 YR4 now unlikely to hit Earth, says ESA

The asteroid 2024 YR4, once considered a potential threat to Earth, is now unlikely to hit in 2032, as new data and observations significantly reduce the impact risk, easing fears of a massive asteroid impact.

Odds of impact of newly discovered asteroid rise increase slightly again

Initially, the probability of an impact was 1 in 83, which represented a 1.2% chance of collision. The odds have now increased to 1 in 43, or a 2.3% chance of impact.

UN Agencies track 2024 YR4 asteroid as 2032 collision risk remains low

YR4 is currently rated a 3 out of 10 on the Torino Impact Hazard Scale, which signals a close approach and the need for ongoing monitoring, with a probability of impact greater than 1%.
