What is the current probability of asteroid 2024 YR4 colliding with Earth in 2032, and why is this significant?

Asteroid 2024 YR4, initially assessed with a 3.1% chance of impacting Earth in 2032 by NASA and 2.8% by the ESA, now has a revised 1.5% chance of collision based on new observations. This surpasses the previous record held by Apophis, making 2024 YR4 the riskiest asteroid detected in two decades. The discrepancy in initial estimations stems from differing orbit determination methods.

How was the Issigau meteorite discovered, and what methods are being used to determine its precise age?

Discovered five years ago in Issigau, Germany, the meteorite's weathered surface suggests it landed thousands of years ago; precise dating is ongoing. Its origin is the asteroid belt between Mars and Jupiter, making it a valuable resource for understanding asteroid composition and potential future mining.
