Despite being large (390 ft, or ~130 meters for us using the metric system), its composition (mostly solid ice) makes it so that in the case of the wrong trajectory and an impact on Earth, most of it is supposed to evaporate and burn; it would quickly be fragmented in thousands of pieces, and have huge impacts in a small area, and almost no impact to the Earth's ecosystem. This is AFAIK, and I am not an astronomer or an expert. Please correct me if I am wrong. Unfortunately there's no Palermo Hazard scale for this particular asteroid [0].

There's some very relevant Wikipedia pages about the subject [1], [2].

So the headline is that a near-Earth object is not only going to miss Earth by a wide margin, but also even if it did hit us nobody would notice...

People would definitely notice. A 390 foot meteor bursting into many smaller meteors is still going to be a spectacular show (and likely cause some damage.)

It's just not going to be an extinction level event.

Even a 390 ft nickel-iron meteor would only be dangerous if it entered over populated areas and the odds of that are low.

Well, assuming my very basic math is right. As said, I am not an expert, and I might be very wrong about how that scenario would have played out.
