The James Webb Space Telescope has taken its first look at the near-Earth asteroid 2024 YR4 before a perilous close approach in 2032. The telescope confirmed Earth is safe, but there is a 3.8% chance that our moon may be in trouble.

The city-killer asteroid's Moon impact risk has almost more than doubled, according to new NASA reports. Here's what we know.

The near-Earth asteroid 2025 BC10 will pass safely near our planet on Saturday (April 5). The Virtual Telescope Project will livestream views of the asteroid's close approach online.

2024 YR4 may not make catastrophic history, but it did set a new record for the JWST as the smallest object ever targeted by the telescope. It’s also one of the smallest space objects to have its size directly measured.

Astronomers have gotten a glimpse of the "city-killer" asteroid before it disappears until 2028, according to NASA.

Shortly after it was discovered, astronomers calculated that the asteroid had a 1-in-83 chance of hitting Earth in 2032 — that's an impact risk of around 1%. Experts urged caution, though noting that the impact odds were likely to fall significantly. Sure enough, by late February, the probability of the asteroid hitting Earth fell to near zero.
