I've been discussing this asteroid with our ham radio think tank the past few weeks. It is not a matter of if it will hit us but a matter of when. Stay frosty and prepare for the worst because it is coming.

Quoted:
They know what Pluto is. They decided to redefine the word "planet" not to include the class of objects which Pluto belongs. The classification of pluto has nothing to do with the predictive ability of science, but rather, shows the centuries old hissy fits that people get in to classifying things using arbitrary categories. When you get down to objective reality, the universe doesn't give a shit what is called a planet and what isn't. All of them are just bits of matter whipping around the solar system. We are the only one who care if it is called "a planet" or "a dwarf planet" or "a huge fucking asteroid" or "a space rock" or "your momma", or any other arbitrary name that we give to things for our convenience and understanding. All of this has nothing to do with the accurate calculation of orbits of near earth objects, which is what this article is attempting to talk about (and failing).

While no one knows for sure what the effects will be, all the simulations we've run with a hamster and a sledge hammer tell us it will be bad.

Poorly written article and/or reporter is too stupid to understand what the scientist was saying. Sounds like collision was ruled out in 2029. The next flyby after that is what is in doubt. Article too poorly written to be sure. View Quote |

2029 ?
I'm good with that timeline. Should be all set, be 100% prepped, and even have a bunker / fallout shelter by then.. hopefully it lands on D.C.. |

Yeah, I know. That was a comet. Look at the bright side. Millennials won't have to worry about not getting SS. Quoted:
It's only 1200 feet across. It's a city killer, not a planet killer. If it hits a few hundred miles away, you will will hear a bit of a boom and some ground shaking, then go back to what you were doing. View Quote Earth Impact Effects Program Robert Marcus, H. Jay Melosh, and Gareth Collins Please note: the results below are estimates based on current (limited) understanding of the impact process and come with large uncertainties; they should be used with caution, particularly in the case of peculiar input parameters. All values are given to three significant figures but this does not reflect the precision of the estimate. For more information about the uncertainty associated with our calculations and a full discussion of this program, please refer to this article Your Inputs: Distance from Impact: 483.00 km ( = 300.00 miles ) Projectile diameter: 366.00 meters ( = 1200.00 feet ) Projectile Density: 3000 kg/m3 Impact Velocity: 17.00 km per second ( = 10.60 miles per second ) Impact Angle: 45 degrees Target Density: 2500 kg/m3 Target Type: Sedimentary Rock Energy: Energy before atmospheric entry: 1.11 x 1019 Joules = 2.65 x 103 MegaTons TNT The average interval between impacts of this size somewhere on Earth during the last 4 billion years is 9.6 x 104years Major Global Changes: The Earth is not strongly disturbed by the impact and loses negligible mass. The impact does not make a noticeable change in the tilt of Earth's axis (< 5 hundreths of a degree). The impact does not shift the Earth's orbit noticeably. Atmospheric Entry: The projectile begins to breakup at an altitude of 54000 meters = 177000 ft The projectile reaches the ground in a broken condition. The mass of projectile strikes the surface at velocity 16.4 km/s = 10.2 miles/s The impact energy is 1.04 x 1019 Joules = 2.48 x 103MegaTons. The broken projectile fragments strike the ground in an ellipse of dimension 0.951 km by 0.672 km Crater Dimensions: What does this mean? Crater shape is normal in spite of atmospheric crushing; fragments are not significantly dispersed. Transient Crater Diameter: 4.76 km ( = 2.95 miles ) Transient Crater Depth: 1.68 km ( = 1.04 miles ) Final Crater Diameter: 5.86 km ( = 3.64 miles ) Final Crater Depth: 504 meters ( = 1650 feet ) The crater formed is a complex crater. The volume of the target melted or vaporized is 0.0654 km3 = 0.0157 miles3 Roughly half the melt remains in the crater, where its average thickness is 3.68 meters ( = 12.1 feet ). Thermal Radiation: What does this mean? The fireball is below the horizon. There is no direct thermal radiation. Seismic Effects: What does this mean? The major seismic shaking will arrive approximately 1.61 minutes after impact. Richter Scale Magnitude: 6.9 Mercalli Scale Intensity at a distance of 483 km: III. Felt quite noticeably by persons indoors, especially on upper floors of buildings. Many people do not recognize it as an earthquake. Standing motor cars may rock slightly. Vibrations similar to the passing of a truck. IV. Felt indoors by many, outdoors by few during the day. At night, some awakened. Dishes, windows, doors disturbed; walls make cracking sound. Sensation like heavy truck striking building. Standing motor cars rocked noticeably. Ejecta: What does this mean? The ejecta will arrive approximately 5.47 minutes after the impact. At your position there is a fine dusting of ejecta with occasional larger fragments Average Ejecta Thickness: 40.6 microns ( = 1.6 thousandths of an inch ) Mean Fragment Diameter: 561 microns ( = 22.1 thousandths of an inch ) Air Blast: What does this mean? The air blast will arrive approximately 24.4 minutes after impact. Peak Overpressure: 1700 Pa = 0.017 bars = 0.241 psi Max wind velocity: 3.98 m/s = 8.9 mph Sound Intensity: 65 dB (Loud as heavy traffic) Damage Description: Glass windows may shatter.

Uh oh. http://www.foxnews.com/science/2017/06/28/scientists-cant-rule-out-collision-with-asteroid-flying-by-earth-in-2029.html "Asteroids are one of the most serious threats to life as we know it, but scientists and skywatchers have gotten pretty good at predicting exactly when and where the dangerous rocks will appear, and how close they're going to come to our planet. One massive space rock, called 99942 Apophis, is going to make a very close pass of Earth in 2029, and that flyby could determine the fate of our planet in the not-so-distant future. "We can rule out a collision at the next closest approach with the Earth," Astronomer Alberto Cellino told Astrowatch. "But then the orbit will change in a way that is not fully predictable just now, so we cannot predict the behavior on a longer timescale." The flyby in 2029 will be extremely close, with the rock expected to pass within 20,000 miles of Earth's surface. That's a ridiculously close shave by space standards, and it's such a tight squeeze that the gravity of Earth is expected to alter the path of Apophis in such a way that its future passes will become much more unpredictable until further forecasting can be accomplished."

Quoted:
Um, there won't be (probably) much fallout, assuming no radioactive isotopes in the asteroid before impact, but even discounting the possibility of heavy metals and organics, the impact of that much rock moving at ~21 mile per second will release a LOT of hard xrays. "EMP" doesn't even begin to describe that size of a burst. That said, you're right that anyone more than a couple hundred miles away will be more worried about the nuclear winter than the impact itself. View Quote View All Quotes View All Quotes Quoted:
Quoted:
It doesn't matter. Anyone who keeps up with YouTube lately knows that Yellowstone is about to blow and we are all toast but the evil government is keeping it a secret. A 1200 ft diameter asteroid falling into your neighborhood is not a good thing but I don't think it will be an extinction level event. The asteroid that created the KT boundary extinctions is estimated at about six miles across if I remember correctly. Even if the 750 megaton estimate is close to correct it is on the order of 15 Tsar Bombas without the radiation or EMP. Bad news for the locals for sure but not the end of the world. Whether or not the estimate is correct depends on the composition of the asteroid and whether it explodes in the atmosphere or impacts the earth among many other things. There is absolutely no real news here because there are no real facts. It is a typical story from the MSM created to generate fear and glorify ignorance and the notion that only a very powerful government can save us. That said, you're right that anyone more than a couple hundred miles away will be more worried about the nuclear winter than the impact itself. At 50 miles from impact, windows will break. |

Smaller pieces burn-up/explode before they reach the ground. So yes buckshot would be better. View Quote From Wikipedia: "The Tunguska event is the largest impact event on Earth in recorded history. Studies have yielded different estimates of the meteoroid's size, on the order of 60 to 190 metres (200 to 620 feet), depending on whether the body was a comet or a denser asteroid." It is supposed that it was an air burst with the energy focused downward, amplifying the effects. Half a dozen of those would not necessarily be better than a big rock hitting the ground. |

Apophis; Proper noun. (Egyptian mythology) The Greek name for the Egyptian mythological figure. The Egyptian name is Apep. Apep or Apophis Ancient Greek: also spelled Apepi or Aapep) was the ancient Egyptian deity who embodied chaos ( Izft in Egyptian) and was thus the opponent of light and Ma'at (order/truth). He appears in art as a giant serpent. Isfet or Asfet (meaning "injustice", "chaos", or "violence"; as a verb, “to do evil” is an ancient Egyptian term from Egyptian mythology used in philosophy, which was built on a religious, social and political affected dualism.
