Asteroid Apophis 2029/2036

[Trund]

Just yesterday, News have been released that the size and mass of Apophis is bigger than expected. It's 25% bigger and has a 75% higher mass.

 

I know that some people on here have been looking forward to some nice and shiny fireworks in the year 2036, but as a new research now shows, Apophis will miss the earth by 14 up to 35 million miles.

 

 

Based on revised orbit calculations, he says Apophis will then come no closer than about 14 million miles — and more likely miss us by something closer to 35 million miles.

 

However, in the year 2029, when it passes the earth the first time, it'll still come quite close with about 20.000 miles. I guess this will at least end the horrible fear of some people that actually thought it will collide with earth!

 

What interests me though is, if the change in size/mass has any effect on the direction of the Asteroid, unfortunately it's not posted anywhere.

20,000 miles is pretty much right on our front door, so we should be a little concerned. But at the same time, there's nothing that can be done to stop a f*cking asteroid hitting the planet.

20,000 miles. Margin for error = 20,001 miles each way

Dude, have you never seen Armageddon?! It can be done.. with the sole sacrifice of Bruce f*cking Willis. Count me in on that crew!

 

Cause I'm leavingggg on a jet plane... don't know when I'll be back againnn.

will the apophis thing be destroyed before it reaches the earth?

will the apophis thing be destroyed before it reaches the earth?

Nuclear weapons are futile against a behemoth mountain-body heading straight for earth at MILLIONS of MPH/KMH.

 

The earth is represent by this watermelon. The asteroid is represented by this .50 cal shell. There is nothing that watermelon can throw to stop that f*cker.

tss tss tss we can stop that "f*cker" by lots of means just put some rockets on one part fire and we might get a new moon! it will require a ton of Delta V

Actually, the laws of physics dictate they aren't if the blast can be channelled in a similar way to shaped charges using the Misznay–Schardin effect. Depending on method of channelling an asteroid up to several miles in diameter could be split quite cleanly, or effectively redirected with a great deal of force.

[MIKON8ERISBACK]

Are you kidding me? I'm glad the asteroid is missing. It means mankind and all of it's great accomplishments, current milestones, and future milestones won't come to a sudden rude collapse. I know we've done some regrettable things with our planet here and there, but anyone hoping for mankind's demise needs some serious psychological help.

WHY DON'T WE TAKE EARTH AND PUSH IT SOMEWHERE ELSE.

cuse the gravity from Earth will still lead it to us

Anyone remember this one? http://articles.cnn.com/2002-06-20/tech/as...home?_s=PM:TECH

[fridaynightscream]

Well at least we get 10-15 years to worry about it.

[Audiophile]

At least we will all die together.

 

This is fate.

Hm. Lets see. If my math is correct, at 1.3kW of solar power per square meter of asteroid's surface and at albedo of 0.23, this puts absolute magnitude of Apophis as it passes Earth at +50.49.

 

Distance of 20,000 miles gives apparent magnitude adjustment of -49.91. And that gives us apparent magnitude of 0.58.

 

 

That's pretty bright, and much brighter than the old predictions of 3-something. You'll have no trouble seeing Apophis with unaided eye. For comparison, only 10 visible stars are brighter than that.

 

Doing a bit more math, Apophis will buzz us going 5.14 km/s. That means it will be moving through the sky just a few times slower than a minute hand on the clock. Not so fast that you'd really see it move, but fast enough for you to notice that it shifted if you check back on it just a few minutes later.

 

 

Should be an interesting sight.

So what you're saying is that the Earth can avoid being hit by the asteroid by not being in the shot when the asteroid goes by?

 

Where are we going to get a washing machine big enough to pull off that shot, though?

It's just 300 meters across, ok? A little more than three football fields. And relative to Earth, it's traveling at a few thousand mph. Not MILLIONS!!!!!!111ONE

 

A nuke would evaporate a good chunk of it, deflecting the rest sufficiently to avoid collision. Nor would the impact of Apohis with Earth be catastrophic. 1 ton of asteroid translates to around 15 ton of TNT equivalent. That puts Apophis impact at 150MT. That's just 3x more than the largest nuke we've detonated. Granted, if it hits a city, it won't be pretty. But if it falls in the ocean, which it has 3:1 odds of doing, we'll barely even notice.

 

Aphophis does not and never has presented any real danger.

and if that fails there's always chuck norris

[Adriaan]

Guess we'll get to play Agent after all.

[Algonquin Assassin]

2029 is 16 years away. Me no care.

[DeeperRed]

But if it falls in the ocean, which it has 3:1 odds of doing, we'll barely even notice.

Would be a f*cking sight to behold though. I wouldn't want to be too close, but to see a largeish meteor crash into the ocean would be prety orgasmic. Though I am sure the displaced water would be similar to a tidal wave, so yeah not too close

The asteroid will miss the earth on 2029 but will come back 6 years later

 

It will eventually hit earth on 2036

Actually, it's pretty much impossible for it hit the earth in 2036.

[GTA_stu]

Yh the chances of it hitting us are ridiculously small. I think a lot of the collision talk stems from the fact that when it was first discovered in 2004, there was initially believed to be a much higher chance of it hitting us, of about 1 in 50. Now it's like 1 in 7 million. By the way people act when the chances are that small, I dread to think what the response would be if it was more like 50/50, or if it was certain to hit us. I think we'd destroy ourselves through the sheer pandemonium and mass hysteria, before the damn thing even got close to us.

Well,that is only an assessment and I don't really believe NASA words sometimes.

 

But your right ,there are less than one in a million chances that Apophis will hit our planet in 2036.

[roebuck34]

good terrans we should be more worried about solar storms as they can burn us like a hotdog as 2013 is the peek of a long time with alot of solar activivty!

It doens't look at all like that anymore, of course you will only know for 100% after 2029, but the chances for it are basically non existent anymore.

Solar Storms are only dangerous if you're in space. Besides destroying electrical devices on earth it's pretty much harmless for us.

The peak is a joke anyways, it was expected to be in 2012, but as nothing happened they now pushed it back to 2013, and as of now there's nothing happening either. The sun spots usually give a good idea of what's going to happen, but those are pretty constant right now, 11 years ago there were a ton more. They made a drama out of this like the world ending last month, and nothing happened.

 

One thing for sure is that we'll get another ice age eventually. But that's caused due to the eliptical orbit of the earth around sun, which increases slowly and eventually we will be so far away the sun, that in summer the arctic ice won't melt anymore. But that's in a few thousand years, and we are pretty much making sure with our global warming that this won't happen anyways. It's arguable whether this is a good or bad sign.

[fridaynightscream]

So wait, is it hitting the Earth and killing us all or not?

[sivispacem]

Not.

That is good to hear.
