Elenin, the new scaremongering is approaching

  1. Jul 30, 2011 #1
    The name of the comet Elenin C/2010 X1 does not show up in PF. I don't know if that is caused by active deletions of the mentors or that the scaremongering has not yet reached PF. But just google Elenin to find a lot of end-of-the-world speculations.

    Better to take note of some facts before the doomsayers are swarming the place.

    I had read about the comet, but not the scaremongering. Thanks for the pre-emptive post.

    Thanks for the heads-up Andre-I haven't been keeping up with comets much. There is a lot of woo-woo out there.

    I got a little bored and started exploring the Woo sites. One person believes that NASA is lying about the comet and is using it to deflect the "real" information, which is that a brown dwarf with satellites is going to plow through the Solar system, disrupting the Earth's orbit in the process.

    Yep. I heard about this. "Brown Dwarf" coming to shake up and flip us and shoot radioactive debris. It's all PLAUSIBLE, but I think the theory of us being beat up by a rouge star is stupid. me, myself, don't believe it'll harm us. But, hey, let the conspiracy theorist who think that we'll all die believe what they want. They've been disappointed so many times before anyway.

    There are two definitions of the word "plausible."
    1. Seemingly or apparently valid, likely, or acceptable; credible
    2. Giving a deceptive impression of truth or reliability

    Perhaps you could argue it's the second definition, but certainly not the first. And, given the fact that there are no brown dwarves in the the vicinity of the solar system, even the second usage of the word is inappropriate.

    The word you're looking for is "silly." As in: "It's all SILLY."

    EDIT: At a billionth of the tidal forces of the moon, I look forward to hearing earthquake and tsunami claims.

    The last link(url) from "universetoday.com" states, "Why Can’t I Find Information of Elenin at the NASA Website? Because NASA is not the arbiter of all things astronomical. You won’t find information on C/2009 P1, C/2011 C1 or any of the faint comets discovered during 2010 and 2011. NASA does have information of comets that its spacecraft have visited, or are interesting in some other way, but it’s not an exhaustive comet site like Cometography or Aerith."

    Well, the universetoday.com was wrong. NASA's Jet Propulsion Laboratory stated on May 4, 2011:


    I hope Andy Resnick gets an image of that comet! Maybe I will too.:smile:

    With respect to Comet Elenin, you can use the interactive controls of this JPL applet to see the position of the comet within the solar system along its timeline.
    http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=2010x1&orb=1

    Here is the discoverer's website, with latest updates on his comet. The overall diameter of the coma is now about 200,000km, making this comet the second biggest object in the solar system at present, although the nucleus is only 2 or 3 km in diameter.

    Thanks Steve for the contribution here on this topic. I appreciate your interest.

    NASA’s STEREO (Solar TErrestrial RElations Observatory), which is the third mission in NASA's Solar Terrestrial Probes program (STP), has this to say:

    Current length of the ion tail is 3,000,000 km, quite a bit short of the record of Hale-Bopp at 50,000,000 km. Elenin will pass within 35,000,000 km of Earth on October 16 of this year. Earth has passed through comet tails in the past, and nothing terribly notable has been reported to my knowledge.

    Not sure if its been covered, but is this one that can be seen with the naked eye when its at its closest?

    That's actually a good question! This comet is fairly dim right now, but long period comets, which Elenin is, will often flare up and put on a show when entering or leaving the inner solar system. So we have our hopes up.

    But undoubtedly someone with good eyes in a good location will see it, even if it doesn't flare up.

    Yes, when it bursts into flames as it contact the upper atmosphere you should be able to see it pretty well from outside of your bomb shelter. When it hits your bomb shelter you should be able to see it pretty well from inside your bomb shelter.

    SO MUCH FOR DOOMSDAY: Comet Elenin (C/2010 X1), widely known for inaccurate reports of its threat to Earth, appears to be breaking apart. Observations by amateur astronomer Michael Mattiazzo of Castlemaine, Australia show a rapid dimming and elongation of the comet's nucleus akin to that of Comet LINEAR (C/1999 S4), which also disintegrated when it approached the sun in 2000. Comets are fragile objects, so this development while unexpected comes as no surprise.

    What's the liklihood the ice and dust slewed off, but a rocky core remains intact?

    We may get lucky and learn more if we can spot and study any elusive remnants as they whiz past. The initial estimates of a kilometer or two for the diameter of Elenin's nucleus may have been rather optimistic. If so, what's left now may be no more impressive than a truckload of gravel. Long period comets are unpredictable cosmic jokers - not good material on which to place bets or predictions.

    Well, Elenin is dead; it's official... the comet came SOOOO close to destroying Earth, that the world's nations secretly joined together to destroy it without spilling a drop of information to the public!

    See? By reading between the lines, you can find the truth!!
