2012 DA14 WILL hit earth.. Confirmed. | |
Dr. Astro Senior Forum Moderator User ID: 33360181 United States 02/12/2013 01:23 PM Report Abusive Post Report Copyright Violation | Actual the estimate of its size HAS gone up from 45 to 65 now. Quoting: Anonymous Coward 203352 In fact NASA is saying 90m max. The asteroid is not physically increasing in size. Our determination of its size is only approximate and is based on our calculation of its absolute magnitude. Right now that is mag 24.1 by the minor planet center's calculations, which for an asteroid with an average albedo of about .15 is about 51 meters in size. We will have a much firmer idea of the size from radar observations that will be performed starting on the 16th. Why do you say WE so much and (our determination). It seems you are part of NASA. I say we so much because I'm not the only one doing these calculations. Neither is NASA. I'm an amateur astronomer. I am not part of NASA. Seems you have an agenda to discredit me. |

"...because Marines kill every-thing-we-see!" |

Quoting: Anonymous Coward 203352 So with that increase in diameter, the MASS surely has to be recalculated unless they are saying the density is 1/8 of what they thought. Its mass is irrelevant. why? Because it will experience the same amount of attraction from earth regardless. Physics 101. Even if it were a kilometer wide it still wouldn't have enough mass to detectably affect earth itself. Well, then you should say the mass is "effectively" irrelevent, not totally. |

Anonymous Coward User ID: 34249200 United States 02/12/2013 01:25 PM Report Abusive Post Report Copyright Violation | Has anyone ever debunked David Dunham's assertions (as transcribed by Russia’s Izvestia) last year at Moscow’s University of Electronics and Mathematics that: "The Earth’s gravitational field will alter the asteroid’s path significantly. Further scrupulous calculation is required to estimate the threat of collision. The asteroid may break into dozens of small pieces, or several large lumps may split from it and burn up in the atmosphere. The type of the asteroid and its mineral structure can be determined by spectral analysis. This will help predict its behavior in the atmosphere and what should be done to prevent the potential threat." Also, I wonder what kind of influence Mercury' accelerating orbit has had on DA14? |

No. It's going to pass inside the orbits of our communications satellites from south to north. If it manages to hit anything up there (extremely unlikely) the debris will most likely avoid those sats. |
Son of PC User ID: 33127834 United States 02/12/2013 01:40 PM Report Abusive Post Report Copyright Violation | Could this discharge of current alter it's course? The break up could alter it's course, too. It is possible that there could be an earth impact of some fragments? When objects come close to the son we witness a plasma discharge. Could the earth itself emit a discharge of some sort of energy that would affect it , alter it's flight trajectory and cause impact? Lot's of questions here. No real assurances of impact or non impact seem possible. |
Dr. Astro Senior Forum Moderator User ID: 4211721 United States 02/12/2013 01:42 PM Report Abusive Post Report Copyright Violation | What about it? Previously the uncertainty region included our geostationary and geosynchronous satellites. Those satellites are at high risk of a domino effect should one of them end up getting hit. Now we know the orbit passes inside the orbits of those satellites. You seem to act like it will either hit one or the other. That's completely wrong. Space is huge, even the space between earth and our geostationary satellites is huge. |

Quoting: Son of PC 33127834 No real assurances of impact or non impact seem possible. That's because you have a fundamentally screwed up understanding of astronomy. Oh well. Actually, I know almost nothing of astronomy. But I did predict the destruction of New Orleans the year it happened before a live witness, but missed by one month. A stunning prediction, not well documented. All I am saying here is that the object could possibly hit the earth. If it did, chances are that it would impact water. Also, there is the possibility of an air burst of some type, like happened in Siberia in 1908. So, if you see a large burst of light in the air don't stare at it. |

Programs that update over the net are suspect, install it fresh with no updates and plug in your variables if they match up then no worries if they don't well then it's suspect of course. I refresh operating systems every month with ie wipe the entire pc reinstall fresh with all security patches already installed. Hackers is a epidemic, and you would be amazed at what goes on in that world. I've seen clean operating systems or programs get changed overnight. It wouldn't be out of the realm of possibilities that a program gets updated to give statistics for amatures or even pros. That's what the fuck I'm talking about. Install fresh no updates do your calcs and then correlate that's how science is done. Measure twice cut once. |

Physics fail. If it were a significant fraction of the earth's mass then the mutual attraction would be noticeably greater, but that is not the case here. Its mass is irrelevant compared to earth's mass. |
