The phrase 'city-killer asteroid' has quickly gone viral online after scientists tracked a near-Earth object known as 2024 YR4, triggering widespread curiosity and concern. While the dramatic nickname might sound like something out of a disaster film, space agencies insist there is no reason to panic.
Asteroid 2024 YR4 was first detected in December 2024 and immediately caught astronomers' attention because of its size and early trajectory calculations. Initial estimates suggested a small chance that it could collide with Earth in December 2032. Those calculations placed the asteroid briefly high on the Torino Impact Hazard Scale, which scientists use to measure potential impact threats.
