when an asteroid passes near a massive object like a planet, its trajectory is deflected, and any existing uncertainty in its path increases. Before the latest radar measurements of Apophis ...

The rate places its risk of collision above Asteroid 99942 Apophis, the "God of Chaos", discovered in 2004 that was given a 2.7 percent chance of hitting Earth by 2029. NASA’s Center for Near ...

However, as with Apophis, astronomers expected the risk for 2024 YR4 to spike and then fall to zero as they obtained more observational data to reduce uncertainties about the asteroid’s path.

An infamous asteroid known as 2024 YR4 won't be crashing into Earth, but the James Webb Space Telescope recently went to get ...

The threat from near-Earth asteroid 2024 YR4 may have subsided, but discoveries of other hazardous space rocks are set to ...

Until scientists have a better understanding of the asteroid’s path around the sun ... clear to another potentially worrisome asteroid, Apophis, after new telescope observations ruled out ...

2024 YR4 may not make catastrophic history, but it did set a new record for the JWST as the smallest object ever targeted by ...

Dr. Jung remarked, "As of January, the anticipated path of the asteroid was expected ... to converge to zero over time. In fact, the Apophis asteroid, discovered in 2004, was initially estimated ...

it was always the plan for the Webb telescope to rendezvous with YR4 in March to get better data on its size and flight path. The asteroid is now the smallest object ever observed by Webb – an ...

It was the highest risk assessment an asteroid has ever received, after the 2.7 per cent chance of Apophis hitting in 2004 ... Our understanding of the asteroid's path improves with every observation.
