The threat of a newly discovered asteroid has risen slightly in the past few weeks, as the world’s telescopes rush to track its course. But the chance of an impact is still quite slim.
New calculations suggest there's a 2% chance the space rock 2024 YR4 will smack Earth in 2032. This also means there's a 98% chance it will safely pass our planet. The odds of a strike will almost certainly continue to go up and down as the asteroid’s path around the sun is better understood, and astronomers said there's a good chance the risk likely will drop to zero.
