YR4 has a very small chance of striking Earth when its orbit briefly intersects our planet's in December 2032.

Around 600 million years ago, Earth was home to strange, soft-bodied sea creatures, but a powerful asteroid impact in what is ...

Once the new measurements were taken and the math was done, the probability of YR4 hitting the Earth began to decline, ...

The 700–1,300 feet-wide space rock deformed rocks more than six miles from the impact site when it hit 600 million years ago.

As an asteroid mining start-up's latest mission goes awry, Josh Sims look at how close we really are extracting rare minerals ...

In reality, even as the near-Earth asteroid 2024 YR4 was moving away, ground-based telescopes were able to gather enough observations to get a better handle on its orbit. So we can safely take a deep ...

New observations have dramatically reduced the chances of asteroid 2024 YR4 hitting Earth in 2032, lowering the risk to minimal levels, but its extraordinarily close approach will offer astronomers th ...

The world wasn’t in need of another reason to panic, but asteroid 2024 YR4 gave them one anyway. It was first spotted at the end of last year, and in the days that followed it went from minor ...

New observations of a small asteroid discovered in December have led astronomers to conclude that the chances of it striking Earth are almost zero after earlier data had indicated a higher risk of a ...

A 500-foot- wide space rock could inflict mass casualties across a state or a small country; those arrive every 20,000 years.
