Asteroid Collision Risk and Detection
An asteroid named 2024 YR4 has been identified as having a 2% chance of colliding with Earth on December 22, 2032. This figure, which is above the threshold that triggers significant concern, was determined using the Asteroid Terrestrial Impact Last Alert System (ATLAS) based in Chile. The detection process involves astronomers comparing images over time to identify moving objects against the static backdrop of stars. The ongoing analysis of the asteroid's orbit presents a dynamic situation, with estimates of collision risk fluctuating as more data is gathered.
