[QUOTE="heka2015, post: 158830, member: 7351"] [URL='https://ssd.jpl.nasa.gov/sbdb.cgi?sstr=2012%20TC4;old=0;orb=1;cov=0;log=0;cad=0#orb']JPL - Jet Propulsion Laboritory[/URL] [URL='https://cneos.jpl.nasa.gov/sentry/%20(enter%202012%20TC4%20-%20no%20filter)']CNEOS - Center for Near Earth Study [/URL] (2012 TC4) Impact probability: 7.2e-5 V relative to earth: 6.51 km/s Absolute magnitude: 26.7 mag Estimate diameter: 0.015 km Torino Scale: 0 More precise estimate here, 15 meters again NASA prefers multiple choice. The Torino Scale needs a little rethinking, if an Asteroid of just 18 m and 12 000 t can deliver a 500 kt blow, even more if the estimate of frequency of such impacts is higher by the magnitude of ten. Asteroids are classified 0 only because their "supposed" kinetic energy is below 1 Mt. Chebyalinsk classified 0 as well with approx 400-500 kt, that is just crazy if you think Hiroshima had 15 kt (!) of kinetic energy. It needs to be an Asteroid minimum of 66x the Hiroshima bomb to be recognized on the Torino Scale above 0? They should be classified 2-4, and thats a "MERITING ATTENTION BY ASTRONOMERS (yellow)". [URL='https://en.wikipedia.org/wiki/Torino_scale'][SIZE=6]Torino scale[/SIZE][/URL] I agree with you on the meteoroide part, proof is all scattered around, so to speak. You can find plenty of Micrometeorites on house roofs in cities ([URL='http://www.spiegel.de/wissenschaft/weltall/meteoriten-so-finden-sie-ein-exemplar-in-ihrer-stadt-a-1133675.html']Source[/URL]). I do not intent to paint armageddon here. But if you look at the facts it doesn't look like a every day shooting star. An Asteroid of 15 m (10-30m or whatever NASA metric you want to use) with an estimated air blast of 500 kt shouldn't be taken as no threat at all, passing by between 4200 and 170 000 miles, or don't I get the facts right? Evidence indicates the chance of burn up in the atmosphere is not likely, observations suggests an air burst at that size. I hope i provided enough sources on this. A Hardhat isn't that bad of an idea. I would add the usual earthquake drill maybe, just in case. Why not simply inform people, like they do with fire/earthquake/flood/tsunami etc. ? Stay away from windows at least... something in the case of an event in general. But that would people freak out now, wouldn't it? That would have saved a lot of injuries in Chebyalinsk. Even without knowing it coming. [/QUOTE]
