Fifty Meter Asteroid Might Hit Earth In 2098 295

eldavojohn writes "The Bad Astronomer brings word of an asteroid discovered with a tiny chance of hitting Earth. While it's only 50 meters wide, it could have the impact of a 20 megaton bomb. It's still twenty million miles away so if it hits us, it won't happen until 2098. The real story here is how a remarkable telescope, dubbed Panoramic Survey Telescope & Rapid Response System, that went operational in May found its first potential target in our growing impact alert system for Earth."

    The good news here... let me correct myself: the great news here is that Pan-STARRS found this thing at all! From that distance, an object this small is really hard to see, and no other asteroid survey could've found it. That means that as time goes on, Pan-STARRS will find lots and lots of threatening objects.

      How you measure the unknown? It IS optimist, saying that we now finally have tools to start discovering this kind of threats. Anyway, that we are getting aware that things could get close don't mean that anything will hit us (in last century nothing similar to that size, so odds should be pretty low).

    An impact by something like that is about the same as exploding a 20 megaton bomb.

    So yeah, bad.

    Wiki [wikipedia.org]:

    The largest nuclear weapon ever tested was the "Tsar Bomba" of the Soviet Union at Novaya Zemlya on October 30, 1961, with an estimated yield of around 50 megatons.

    So this impact would be 40% of the Soviet test. How badly did the Soviet test harm the Earth?

      Well, for one thing they never tested in the middle of a heavily populated area, if the stone should choose to fall in a city and not the ocean. A bigger concern would be if said explosion happened in a nation with a paranoid dictator who lets the nukes fly because he thinks he's under attack, cascading into everyone following suit.

      It wouldn't be an extinction level event or anything like that, but it would almost certainly ruin the day of anyone nearby where it did hit. And even if we could get advanced warning of where it would hit and evacuate all the people, if it heads towards a city, that's a lot of property/infrastructure/housing that will be obliterated. So not necessarily catastrophic, but probably not particularly great either.

      Although if we figured out that it was going to hit somewhere basically unpopulated and un-utilized

      That test was an air burst. In any case a nuclear weapon delivers its energy as heat while a meteorite delivers its as kinetic energy so the effects are not going to be the same even when the energy is.

      • by Nadaka (224565)

        Heat is kinetic energy.

      • by tibit (1762298)

        Methinks a lot of that meteorite's kinetic energy will be tranformed into heat almost instantly upon impact, vaporizing a lot of stuff. It's the blast -- the heat-induced expansion of atmosphere and vaporized material that will create most damage methinks.

      Depends on where it hits. A single 50 megaton nuclear bomb doesn't really do much to the earth, long term. Obviously, the Soviet bomb hasn't had any lasting environmental impacts worldwide. However, they exploded that bomb near the Arctic Circle in an unpopulated, desolate place. If it had been in the middle of Hawaii, that probably wouldn't be much of a vacation spot now.

      A 20Mt asteroid hitting in the middle of the ocean would be a big and interesting event, but nothing to be too concerned about. Howe

    From the summary:

    " While it's only 50 meters wide, it could have the impact of a 20 megaton bomb."

    Which sounds impressive - until you realize just how empty the Earth really is. Across probably 80% of the Earth, a 20 meg explosion will produce few (if any) casualties. Doubly so since that size range is likely to breakup and deposit most of it's energy in the upper atmosphere.

    Today countries all over the world cling to ethnic and religious differences as primary societal foundations. As long as that is true we will have never ending war. This asteroid is a gift of a single unifying foundation for all of humankind to unite around. Working together to deflect this asteroid will diminish those cherished divisions along ethnic and religious lines. Once we are done, the young generations will see no reason to go back to hating each other.

      It always intrigues me when people say we will have never-ending war. Have you actually looked at the statistics to see what has happened to war in the past three decades, or the past century? The number of wars has dropped dramatically and consistently. I know it is hard sometimes for a person from the US to see this, since it feels like we've become more warlike since the 90s, but if you actually look at the numbers that's more of an illusion.

      As the remaining fighters realize they have more to gain from trade than from fighting, then wars will continue to cease.

    They JUST found this thing. The amount of data available to determine it's orbit isn't enough to know exactly where it is going. HOWEVER when they dig up some old sky photos they will find earlier positions of this thing. The more earlier data points the better they will be able to predict it's path. Usually this means that the odds of an Earth impact will go down. It's happened before with other newly discovered objects.

    The /. summary reads " It's still twenty million miles away so if it hits us, it won't happen until 2098". This statement seems to imply that because it is 20 million miles away it will take 88 years to get here. That implies a very poor understanding of basic math and science skills. 20 million miles is just not that much in terms of astronomy. The earth is about 93 million miles from the sun, and covers a distance of over 300 million miles each year as it falls around the sun. 20 million miles would not take this rock 88 years to reach us, the real issue is that its orbit and the earth's orbit don't intersect until 2098. Until then the rock may be closer or farther than 20 million miles from us, the 20 million is just a distance it was away from us at one time.

    • by Quirkz (1206400)
      Yeah, that one bothered me, too. I wasn't really sure from the summary if it meant it was only traveling .25 million miles per year (unlikely, but implied) or just that 98 was when the orbits would intersect (more likely, but not as worded).

    I was thinking recently that we were lucky that most of the ecosphere-killing events in our history were astoundingly long ago and that our local space should be pretty clear by now. And then I realized that the dinosaur extinction event that happened 65 million years ago took place when the Earth was about 98.6% as old as it is now. If the Earth was now a day old, the dinosaurs were wiped out at 11:40PM. Suddenly those past catastrophes seemed not as comfortingly ancient.
