Asteroid 2012 DA14 | |
Meggarea User ID: 1585244 United States 12/27/2012 10:37 AM Report Abusive Post Report Copyright Violation | It was discovered at the start of 2012 and is set to travel between the Earth and our geostationary communication satellites on 15 February 2013. At a distance of just 22,500km this will be the closest asteroid ‘fly by’ in recorded history. Quoting: StormeyGoddess Except its' closest approach is actually on the 16th. On the 15th, it is .0034 AU, or 316,000 miles. It will be about .0003 AU or 27,000 miles from Earth on the 16th. That doesn't seem close enough to hit, but why are they lying about the day?

And even that aside, I'm guessing you only looked at the distance at midnight on each day.

They have a very accurate table of the close approach times and distances right below, which shows it on Feb 15, 2013 at 19:25. |

Anonymous Coward User ID: 30956944 United Kingdom 12/27/2012 11:16 AM Report Abusive Post Report Copyright Violation | the simple truth is this if Nasa SAYS it won't hit, it won't hit. wasting time on things like this is just that, wasting time. let's concentrate our efforts on the anomalous weather on earth, or the volcanic activity which is intensifying, instead of wasting efforts on this doom that simply won't happen. it's only 49 metres anyway, hardly doom for us or the moon even if it did hit either. |

It has happened many times before as you can tell. The moon protects the Earth in just that way. Quoting: Anonymous Coward 21548336 that would be fucking good, I agree the moon is da protector of the earth um, no. we have been hit FAR more times than the moon cos we're much bigger than it. weather and tectonics.the great cleansers. |

Quoting: Auroramatista87 30500891 I knew the answer, unfortunately. NO. They would dumb it down to stop mass panic. Especially if there's nothing they nor we can do How do you know this answer? Or, are you just making an assumption based on movies you've seen? |

Not everyone thinks as you do. That isn't what I would do. No proof but I have heard insider testimony that NASAs operational procedure is NOT to disclose any news of impending danger to the planet as it is feared by the higher ups that societal chaos or collapse would ensue... and they are probably right... If you KNEW 100% that there would be a global coastal event on February 15, 2013... because NASA knew and reported an ocean impact zone... wouldn't your priorities change? |
Anonymous Coward User ID: 30403787 United States 12/27/2012 12:47 PM Report Abusive Post Report Copyright Violation | This asteroid has no chance of hitting us. LMAO. NASA would of had thing think deflected by now if it was going to hit. Don't forget, they don't want to die from a dam asteroid impact. Quoting: MayanGod Well I don't expect it to hit us but what makes you think we could deflect an asteroid? That only happens in the movies...we haven't as a nation or a planet invested the resources to develop this capability. |

Anonymous Coward User ID: 30963098 South Africa 12/27/2012 01:27 PM Report Abusive Post Report Copyright Violation | I have never made a prediction before, but here's some food for thought... Quoting: StormeyGoddess We've had soooo many astronomers point out that Asteroid 2012 DA14 will not hit Earth, but what are we missing???? Is there a better chance of 2012 DA14 hitting our moon!!!!! Astro, where are you on this????? Maybe Doom is still on?! It is on course for a near...very near miss...but what everybody seem to forget is that our gravitational field might pull it in. Also how will the moon affect the orbit of DA14 |

Well, sure I read the disclaimer, but I was not trying to use it for long term predictions, or to decide if it was going to hit anything. I already know it won't hit us. :) I am not exactly a rocket scientist, though, and this was a bit different than any I had seen previously, so I was a little concerned. Just so that I am clear, how close will it be on its' closest approach? Thanks, by the way. You help keep my inner crazy person in check. |
