If a mime on a NY sidewalk is pretending to be trapped in a box, and a local passing by busts his jaw with a quick right, does anyone stop shooting the video with their phone long enough to care?

Haggis I'd better watch that one.

[IronJack]

Suuuuurrrrrre it was. Not the Russians. Or the Norks. Or the Chinese. Not Michael Moore farting. A meteor ...

[Centurion2000]

I don't worry about the 173 kiloton exploding asteroids that enter Earth's atmosphere.

I worry about the 173 PETATON exploding asteroids that might enter Earth's atmosphere.

...and from the depths of YouTube, an omnibus of vids of the 2013 Chelyabinsk bolide.

Feb 15,2013 - A "small" meteorite streaked through the skies above Russia's Urals region. The blast, equivalent to 300,000 tons of TNT, shattered windows, damaged more than 3,000 building and injured over 1,000 people. 8 months after the incident, the meteorite, weighing in at 570 kg, was pulled out of Lake Chebarkul, making it one of the biggest meteorites ever recovered.

Some of those astroblemes will buff right out.

[NativeSon]

Only if it were not Trump’s fault.

[Redcitizen]

With an astrobleme, it’s on sale half off, no returns!

[dp0622]

Wow.

Amazing that all it takes is one really big one to end all of these thread conversations in an instant.

[Ezekiel]

The scary part...for all our watching, no one saw it coming.

Ironic because it lost its berings, so where else would it want to go.

They make a big kaboom. A rock a mile across (depending of course on the velocity) can deliver more pop that all the nuclear arsenals put into a pile and set off simultaneously. The Meteor Crater / Barringer Crater in Arizona was formed by a rock about 160 feet across (about 1/33rd of a mile, hence, other things being equal, about 1/35937 of a mile diameter rock, that's 33 in three dimensions). Boom.

The crater stretches 1200 meters across and 170 meters deep, with the rim of the crater rising 45 meters above the surrounding landscape. The area around the impact site is tinted red with oxidized iron from the nickel-iron meteor which impacted there almost 50,000 years ago. | University of Iowa

A little Bondo, the meteorite will be good as new.

I wonder if any of the Deadliest Catch crab fishermen saw anything.

“And almost nobody noticed.”

Yeah...how close did the Russians come to launching?

[gleeaikin]

This is a fascinating book and well worth reading. Question? Was this explosion more or less than the Tungusku (sp?) meteor? Also, what would it have done over an urban location?

[Cvengr]

173 kt vs 440kt (Chelyablinsk), this one was much smaller

[SunkenCiv]

I'm not sure of the altitude at detonation, otherwise I'd take a stab at the level of damage and mortality had it happened over an urban location. Regarding the Tunguska object:

At 7:17 a.m. (local Siberia time), at a height of about 28,000 feet, the combination of pressure and heat caused the asteroid to fragment and annihilate itself, producing a fireball and releasing energy equivalent to about 185 Hiroshima bombs. [NASA Science Mission Directorate]

[SunkenCiv]

Good question... has anyone heard from them since the explosion? ;^)
