More data is better data in this case, and observations allowed astronomers to refine its orbit to determine how much of a threat it posed. Asteroid 2024 YR4 follows an elliptical orbit around the sun ...

Chances an asteroid may hit Earth in 2032 have again risen, though the risk remains tiny, astronomers say. Here's what to know about 2024 YR4.
