2024 YR4, a lump of rock the size of a building, may be heading our way, but don’t start stockpiling the tinned carrots yet

Last Tuesday, Nasa calculated it had a 3.1% chance of hitting Earth in 2032, and so some people set to worrying. Twenty-four hours later, however, the agency provided an update. New observations, made since the passing of the full moon, show it now has a 1.5% chance of impact. Time to exhale? Not necessarily.
