But both percentages rise above the 2.7% chance of collision once associated with an asteroid discovered in 2004 called Apophis, making 2024 YR4 the most significant space rock to be spotted ...

The space rock is formally named 2024 YR4. Scientists say the risk of it making contact with Earth is remote — with NASA giving it as high as a 3.1% chance before reducing its estimate to 0.28% ...

While YR4 still has a nearly 97% chance to completely miss Earth in 2032, its odds of impact, which now stand at 3.1%, represent the highest risk level of any large space rock ever. Those odds may ...

showing the rock in the clearest detail yet. They were taken on February 7 by the Gemini South Telescope in Chile, and show 2024 YR4 as a bright smudge in space —captured while it was 37 million ...
