Re: Asteroid 2012 DA14
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 didn't lie, close approach is at 19:25 UT on the 15th, thus when you look at the distance at midnight on the 16th it's closer than it is at midnight on the 15th. And please don't use the java applet for planetary encounters like this, it's just a two-body quick browse tool. 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.

Hitting the moon would be good. It has happened many times before as you can tell. The moon protects the Earth in just that way.

Re: Asteroid 2012 DA14
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.

Assumption, then.

And, here is the biggest problems with assumptions. You are assuming that our global leaders would keep this knowledge a secret, because that's what you would do. Not everyone thinks as you do.

That isn't what I would do.

No it won't hit us this time but we might want to start preparing for 2020 when it makes a return visit

Let's keep our fingers crossed and hope it misses us then as well
 Quoting: Anonymous Coward 20675367


According to NASA it will not survive this next encounter...

assuming that is the hidden message behind it having no more future approach dates appearing in the close approach table [link to ssd.jpl.nasa.gov]

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?

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.

Remember, when NASA impacted two washing machine sized objects on the Moon not to long ago, they were also not to forthcoming with why they were doing it.

Is it possible that they were getting some numbers to figure out the effect of an asteroid impact???

Re: Asteroid 2012 DA14
I have never made a prediction before, but here's some food for thought...

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?!
 Quoting: StormeyGoddess


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

 Quoting: Dr. Astro


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.
