And it now looks like 2032 is ... going to be another boring, normal year. At least as far as asteroid strikes. The probability of impact by 2024 YR4 is now so low that NASA deems it "No Threat", or 0 on the scales used to measure these things. Good illustration of how science works (or should work) though. There was an initial hypothesis of a given risk after initial observations. Further observations tested that hypothesis by refining that risk, at first upwards but eventually downwards. Truth tested and refined by further observation. And, in this case, a lot of thanks go to Sir Isaac Newton since his law of gravity allows us to, once we have enough observations, calculate an object's orbit to a high degree of accuracy in order to determine if its orbit and Earth's might intersect to the detriment of both orbiting bodies.
The likelihood of asteroid 2024 YR4 hitting Earth in 2032 rose and fell last week. NASA's impact odds are now so slim that the asteroid is no longer a hazard on the Torino asteroid scale.

Footnote: General relativity can do the job, too, but is generally only needed in high gravity fields, e.g. Mercury's orbit due to its close proximity to the sun.
