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.

NASA said that an asteroid previously believed to be destined for Earth is now more likely to make impact with the moon.

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.

NASA has raised the odds that a massive asteroid, about the size of a 10-storey building, could collide with Earth's Moon. Asteroid 2024 YR4, discovered in December 2024, initially posed a potential risk to Earth in 2032.

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.

NASA's James Webb Space Telescope recently turned its watchful eye toward asteroid 2024 YR4, which we now know poses no significant threat to Earth in 2032 and beyond.

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.

A recently discovered asteroid, 2024 YR4, sparked the first-ever global alert from the International Asteroid Warning Network after it showed a small but real chance of hitting Earth in 2032. Finnish astronomers and an international team jumped into action,
