The European Space Agency recently announced that the near-Earth asteroid 2024 YR4 has a 2 percent chance of hitting our planet in 2032. The probability of impact is difficult to predict exactly and will be clearer in 2028, when 2024 YR4 will whiz by us. But if the asteroid really is on a collision course with Earth, what can we do about it? Senior space and physics editor Lee Billings joins host Rachel Feltman to unpack this headline-making story.

  • Foreign for Scientific American Science Quickly, I'm Rachel Feltman.

  • Have you heard that an asteroid might just maybe smack into Earth sometime in the next few years?

  • The rumors are true, though perhaps not as frightening as you might think.

  • The fact is that this asteroid, called 2024 YR4, is both literally and figuratively a moving target.

  • As of February 11,

  • the European Space Agency estimated

  • that the space Rock has a 2% chance of colliding with Earth on December 22,

  • 2032.

  • That's a slightly higher risk than you'll hear quoted in the episode that follows

  • because we recorded it last week.

  • Why are those numbers changing so quickly?

  • We promise this isn't a matter of the risk just going higher and higher as time goes on.

  • It's a lot more complicated than that.

  • Here to explain what's going on with this potentially hazardous asteroid is Lee Billings,

  • a senior editor covering space and physics for Scientific American.

  • Lee, thanks so much for coming on to chat.

  • It's my pleasure as always, Rachel.

  • So there's an asteroid with a very low chance of hitting us.

  • Why did this make such a big.

  • Splash in the news?
