Asteroid Whizzing By Earth 6 Times Closer Than the Moon (cnet.com)

An anonymous reader shares a CNET report: The problem with asteroids passing near Earth is that they're often difficult to spot. Fortunately the hardest ones to see in our neighborhood also tend to be the smaller ones. Such is the case with 2017 BH30, which was discovered Sunday by the Catalina Sky Survey just hours before passing by us at the creepy-close distance of only 40,563 miles (65,280 kilometres). This asteroid is estimated to be between 15-32.8 feet (4.6-10 metres) in length, making it somewhere between the size of a truck and a... big truck. That's pretty small by asteroid standards, but it's also the closest spotted asteroid to pass us since September when asteroid 2016 RB1 passed within 24,000 miles (about 39,000 kilometres) of our planet's surface, putting it almost as close as satellites in geosynchronous orbit. This is the third asteroid to buzz by earth closer than the distance to the moon this year. We don't expect a closer pass by one of these visitors until October, when asteroid 2012 TC4 could come more than twice as close.

      There have been a lot of airbursts. The smaller the meteor, the narrower the window where it will survive to impact the Earth. Too slow or too shallow and angle and it spends too much time in the atmosphere and burns up (like much of our rocket launch debris). Too fast and the energy of hitting our atmosphere fragments it, greatly increasing its surface area and again causing it to burn up. It has to hit the atmosphere at just the right speed and angle to form an impact crater. Fast enough that it doesn't burn up entirely before hitting ground (angle of impact determining how much atmosphere it has to travel through), but slow enough that the stresses of re-entry don't cause it to break up. So most small meteors which intersect the Earth end up as airbursts.

      Suppose serious asteroid impacts happen about once in fifty million years

      Define serious.

      The Barringer/ Meteor Crater impactor (about 14kyr ago) was pretty trivial. If it happened today, probably not even a megadeath. At 1.1km diameter, that gives us a sort of calibration point. Assuming that population impact scales roughly with crater area, then to get a gigadeath (and presumably some pretty large social consequences), you need an impactor leaving a crater of 30km or more diameter. (It's by no means a watertight argument, but it's good enough to give us some idea of what we're facing.)

      From EIB (I can't find a diameter-versus-age sortable table), the most recent suitable candidates I can find are :

      • El'gygytgyn, N 67 30', E 172 5', 18 km diameter, 3.5 ± 0.5 Myr old. A bit small, but recent.
      • Kara-Kul, Tajikistan, N 39 1', E 73 27', 52 km diameter, <5Myr. Disturbingly recent, and well into the "big effects range.
      • Ries, Germany, N 48 53', E 10 37', 24 km diameter, 15.1 ± 0.1 Myr. Doesn't quite reach the size criterion, but this was probably part of a multiple impactor.
      • Chesapeake Bay, Virginia, U.S.A., N 37 17', W 76 1', 40, 35.5 km diameter ± 0.3 Myr Well under your 50 million year W.A.G.
      • Popigai, Russia, N 71 39', E 111 11', 90 km diameter, 35.7 ± 0.2 Myr. A lot bigger than my W.A.G criterion, and still well under your W.A.G. interval.

      I think that you're somewhat underestimating the risk. Particularly since the dearth of discoveries in the southern hemisphere (a sampling effect - less ground there. Consider the Eltanin structure of some 2 million years old (poorly defined at the moment) and 10s of km in diameter (also poorly constrained - the site is on the flank of some seamounts) and on rugged terrain (water depths of 2.5 to 5 km).
