Asteroid 2012 DA14 Will Just Barely Miss The Earth On February 15th, Destructive Potential Of An H-Bomb

January 31st, 2013 by

Asteroid 2012 DA14 is going to just miss the Earth on February 15th. It will pass by at a distance of just 14,913 miles, which is closer than many satellites orbit. If it did strike the Earth, which it may in the future, the 164ft long asteroid has about as much destructive potential as an H-bomb. So if it hit an urban area the damage would be enormous, and that’s not even including side effects such as changes in the weather, and possible tsunamis.

As Don Yeomans, of NASA’s Near Earth Object Program at the Jet Propulsion Laboratory, says: it will be a “record-setting close approach. 2012 DA14 will definitely not hit Earth. The orbit of the asteroid is known well enough to rule out an impact.”

Researchers have estimated that if a strike did occur, that it would level an area larger than all of Greater London. Just back in 1908 there was an asteroid impact of similar size, the Tunguska event. The (estimated) 131ft asteroid completely flattened over 772 square miles of Siberian forest.

“That is an area the size of Greater London,” said Dr. Gerhard Drolshagen, a near-Earth object observer from the European Space Agency’s Space Situational Awareness (SSA) office. “This asteroid is a little bigger.”


Dr Yeomans continued: “Since regular sky surveys began in the 1990s, we’ve never seen an object this big get so close to Earth.”

“The rock in question is believed to be made of stone, rather than metal or ice and Yeomans estimates an asteroid of that sort flies past Earth on average every 40 years, but is only likely to strike the planet ever 1,200 years or so. An estimated 500,000 near-Earth objects measuring up to 98ft are believed to be undiscovered.”

Dr Detlef Koschny, also from the SSA, said: “We are developing a system of automated optical telescopes that can detect asteroids just like this one, with the goal of being able to spot them at least three weeks before closest approach to Earth.”

Unfortunately, even though it will be passing very close to the Earth it will not be visible with the naked eye. It will peak around an apparent magnitude of 7.4.

The asteroid’s orbit will likely be changed to some degree by its very close pass-by, but isn’t expected to pass any closer than 0.0004 AU from the center-point of the Earth on its next pass-by in 2046.

    ALL THAT EVER LIVED ON EARTH WILL SOON HAVE THEIR EYES TO THE HEAVENS

    Do a little History on this one.

    ALL Should Look Up “2012 DA14″.

    This
    could take out one of more satellites and the junk and debris from the
    hit could end up taking out many more satellites very soon after that.
    All the satellite collision probability will go way up if even one is
    hit. The velocity that the parts would go to would make them missiles
    that would start targeting a chain reaction this would not be good.

    Most
    all will be watching this one and pray it goes by us without a hit.
    Every Scientist alive will be watching this event. Many will be in
    Florida for a very special viewing of the once in a Lifetime Event.
    Professors, Scientist, World Leaders, Ham Radio Operators and Every
    Astronomer will have its eyes on This Event, along with almost every TV
    set on Earth.

    “2012 DA14″ goes by Earth
    twice a
    year and there is no way anyone for sure, can tell how close the second
    pass will be till it passes by the Moon and Earth and the GRAVITATIONAL
    FORCE effect that it will have on this Asteroid.

    They may come
    close but this one is already coming very close to begin with. Too close
    this time or on its second or 3rd pass? Ad a Meteor Shower like the 13
    and 14 of December of 2012, it might go through or bump into one of
    them? Or all the other more then 20,00 pieces of orbital debris like
    Spent Rocket Boosters left in space that can no longer be moved by a
    control center on Earth. Or add a Solar Flare. Or a Comet ISON or its
    tail debris of millions of rocks of all sizes. Not to for get the
    30,000+ pieces of space junk left from China in 2007 from showing the
    world it could shoot a decommissioned weather satellite in Space. Now
    add Asteroid 2013 BV15 into this on the 13 &14 of Feb 2013..

    Feb will have 12
    of them from the 12 to the 16.

    If a big enough Asteroid were to slam into the moon in the night sky you would think the sun was coming up early only
    it would be 5 to 7 times as bright. From The Sun’s Rays Reflection on all the Debris Field.

    2012 XM16, 2012 XM55, 2012 XP55, THERE ARE OVER 25 found
    just in the year 2012 that are part of the Near Earth Object
    Program that will come close to Earth from now till 2012 DA14 comes, Feb 14 – 16, 2013.

    You do not want to know how many are on the “PLANETARY DEFENSE” list.
    The PLANETARY DEFENSE is not to protect Earth from men from Mars.
    It
    is for all mankind with most all Nation in on it to stop if can most
    all collision with EARTH from a ASTEROID IMPACT. It is if you will a
    AVOIDANCE SHIELD. “N.E.O.S. Near Earth Object Shield”.

    If only
    one were to hit or IMPACT EARTH on land get ready for a winter you will
    never forget. The winter from 1883 -1884 KRAKATOA you will think was a
    little pebble, and now the stone comes.

    A Shock Wave was felt in England from a
    Event about 7:15 to 7:20 A.M. Siberia time in the morning in June of
    the year 1908 high in the sky above the Forest in the remote wilderness
    of Tunguska Siberia heard an explosion that laid flat more than 800
    square miles of the forest with all the trees pointing away from the
    center of the blast with most all the trees laying on their side. Some
    trees that were right below the blast were still there looking like
    telephone poles with no bark or branches left on them. This Asteroid did not even hit the Ground and this is known by most as the TUNGUSKA EVENT. For all that lived there it was WORMWOOD Rev 8:11 the wood became full of worms and the rivers water no longer sweet and undrinkable.

    If a Meteor Shower is big enough you might think all the Stars are falling from Heaven.

    About one every 100 years makes it into the Earth’s Atmosphere big enough for all to take note. Some make it to the surface the signs are all over the Planet and moon from the ones that have.

    If you need a visual sign of a collided impact with a planet look to

    “SHOEMAKER – LEVY 9″ July 1994.

    You Need More Look up “PROJECT WORMWOOD” Revelations 8: 10 – 11 based on the “TUNGUSKA EVENT” 1908

    MOSCOW Russia is now saying it will use missiles to intercept Asteroid if need be.

    Better to be safe then sorry.

    GET READY

    Read your Bible
    While you still can,
    and May our Lord GOD Bless all that do so.
    John 14 : 6
    Luke 13 : 27
    Matthew 7 : 20 – 27

    Matthew 12:39

    Matthew 24:3 – 14

    The Lord’s Little Helper.
    Paul Felix Schott.

    December 2013 the Heavens above COMET “C/2012 S1″, “ISON”.

    The day will come when

    ALL
    ON EARTH WILL SEE THIS NO MATTER WHERE YOU ARE. the night side of earth
    will become day and and day will be blinding bright. The Bow Shock from
    the Photo Electric Effect from the Sun’s Solar Wind will really be
    something.

    Shortly there after you will think the stars are falling from the Heavens,

    REV 6:13,

    REV 16:21

    most will be between 60 to 80 pounds that will make it to the ground surface. Nonstop 12 to 14 hours at a time for two days.

    P.S.
    Help others in are Lord’s name Jesus Christ help bring all to know him while you still can.Three kings that were wise men once flowed a star with a long tail 2,000 years ago. That lead them to Jesus Christ wise
    men still look to and hear are Lord Jesus Christ.
