It appears that this went unnoticed by most, including some/many astronomers, but early last week there was another near miss by a ranging shot from Klendathu (those bugs are really quite clever, and technologically savvy).
Missed us by only 120,000 miles, or so, with a rock said to be between 35 – 110 feet across.
Astronomers detected it only on Saturday, and apparently it flew by, on Monday, at only half the distance to the moon, so a rather close shave.
Looks like they've got us well bracketed, and it is only a matter of time.
If it had hit the atmosphere, it would have released significantly more power than the atomic bombs on Japan.
If one of those hits a city, it is going to be a bit messy.
Sleep well, silly, distracted humans, while you can.
