Asteroid anxiety: Astronomy's 300-year quest to predict cosmic collisions

On February 18, NASA announced the recently discovered asteroid, 2024 YR4, has a 3.1% chance of striking Earth in 2032. We can sleep a little easier, though, because the following day this was revised down to 1.5%. And the odds were then slashed again down to a reassuring 0.004%, though the chances of the asteroid hitting the Moon in 2032 stand at 1.7%, per NASA’s statement on February 24.

At up to 90 meters (295 feet) in diameter, it was described as a potential “city killer.” On its estimated trajectory, it could’ve collided with Earth as soon as 2032. According to the Torino Impact Hazard Scale, used to characterize such threats, it ranked a Level 3 out of 10 — a highly unusual designation, suggesting a “close encounter” was plausible. Panic is …
