Graphic Shows The Size Of Rosetta's Comet

So the landing was overrated?
 
Hmm, I dig the perspective, but that city doesn't look too big when you consider the comet is 3km wide, almost like they purposefully shrunk the city, 3km is what about 20 blocks or so at most.

If that's true then I call BS on the OP article.

it's 18.6 blocks, according to Google, which makes this comet about half as wide as downtown Denver, or about the same size as Kalimdor in World of Warcraft.
 
my virus web shield goes crazy when I enter this news post. Says threat has been detected

Yeah I believe the picture is of LA. I looked on google maps and measured the 1.8 mile distance, and it looks like it takes up a sizable amount of the downtown area... but I've also never been to LA so I may be off on that.
 
If there ever is a comet that big, I hope the military is fast enough to nuke it to bits.

That's still like shooting a moving target on the moon while strapped to the back of a supersonic jet. Its mad science, yo.

They said it was moving at 84K miles per hour while rotating... yeah, could you pull that off on lunar lander?

The portion of downtown LA with tall buildings isn't really that large, maybe 9 or 10 blocks wide. The city just kept spreading out instead of up. Southern CA just became pretty a solid metropolitan area from LA all the way down to the border, with just a couple breaks in developed areas like USMC Camp Pendleton, which is massive. It's not like, say - Manhattan, where geographical constraints forced the city to build up instead of out.

So if the comet is 20 blocks wide, that picture looks about right to me.

but at the velocity it would impact earth wouldn't be nice
 
GD that is awesome!

But also had my virus block popup with that 3 post in.
 
so this comparison is entirely wrong and anyone could have put this together in 5 minutes. :eek:
 
Can we get a photo city comparison that is correct?
 

Yeah, um... I just crashed the moon into the earth and this is what it said:

"The Earth is not strongly disturbed by the impact and loses negligible mass.
2.67 percent of the Earth is melted
Depending on the direction and location the collision, the impact may make a very small change in the tilt of Earth's axis (< half a degree).
Depending on the direction and location of impact, the collision may cause a change in the length of the day of up to 33.8 hours.
The impact does not shift the Earth's orbit noticeably."
 
BTW... Why are they fucking with this Comet. Is there something they aren't telling us?
 
Imagine trying to shoot an astroid down that is going a net 100kph while the earth is traveling around the sun at 1 revolution per year at 107,000 kph, while the earth is rotating at one rotation per day at 1,666 kph while traveling through space on a parabpolic projection at 675,000 kph.

That's like getting a no scope head shot on a guy who is all the way across the map with a pistol.
 
btw you cannot really nuke asteroids.

Nukes don't do much in space, since there is no air.

The purpose of landing on this thing was to learn about them, and well the origins of formation of the the earth and other solar system objects, since its believe it formed at the start of our solar system.

You don't need air for the explosive reaction, but you do need to contain the explosion, so you'd have to drill into the comet, or use some kind of warhead that can bury itself deeply into the comet before exploding, like the bunker buster bombs on earth.

Homer: Air

Well considering the space craft was traveling at the same speed as the comet, it effectively had a speed of zero. So only have to deal with the rotation.

Sure, but how do you get to the comet in the first place? You have to vector towards it, then you have to change your travel arc while going thousands of miles an hour to perfectly match the comet on a parallel course at an identical speed while you're very far away, no easy task. That in itself is an accomplishment. Then once you've done that, then you can rotate around with it (no gravity for orbit) while inching toward your landing site all with limited fuel onboard for maneuvering.

IMO its super impressive.

So, it's the Jerry Miculek maneuver you're saying :)

I'm not denying it's impressive. And to up the ante on the impressiveness very often they don't change much of anything mid flight, they calculate the ever living hell out of it before it launches, figuring out where everything will be in the next 10 years as it sling shots around everything in the Solar System to arrive where the comet is at the same time and the same speed. It's a feat that would make the most complicated Rube Goldberg contraption creators go "Damn that was bad ass"
 
Imagine what we could do with all that basic elemental material if mined and processed. :eek: We could stop tearing up the Earth for the elements our civilization needs. We need to get into space BIG time!

So um the margarita industry is tearing up the Earth? It's a comet, which is mostly made of ice.

Yes. There is something they aren't telling you. You're paranoid.

Consider yourself informed. Knowledge is half the battle
 
"Mostly" is kinda relative in an object that's several square miles in size.

I think you vastly underestimate the amount of shit we humans burn through. As one small example, mountaintop removal mining:
