Zothecula writes "China has now joined the very select group of countries to have succeeded in carrying out an interplanetary probe mission. According to reports from China's official news agency Xinhua, the Chang'E 2 probe passed a mere 3.2 km (2 miles) from the near-Earth asteroid Toutatis at 8:30:09 GMT on December 13, making it the closest asteroid flyby to date ... and resulting in some remarkable photographs."

Well. Since the summary states this is an interplanetary probe and since I didn't RTFA to verify that is the statement that China issued. I must assume that China is lying since asteroids are not planets and thus this is not a valid interplanetary target.

North Korea's spaceship was doing donuts around the asteroid by the time the Chinese got there. Glorious Leader's spaceship is much faster and more agile than anything the Chinese could come up with.
And obviously, it has even better stealth capability than a Chinese teapot in the same orbit.

Its "faked" because no one likes the fact the chinese do most everything better than everyone else and the "fakes" are usually discovered by americans who need to always prove they are the best country on the planet. Whether it be faking having proof other countries fake stuff so they can feel superior, or rolling in the military to a under forced nation which is like mike tyson in a school yard.

Well, Hayabusa was a specific asteroid probe sent on a seven year mission to an asteroid in its orbit. Chang'E 2 was a lunar orbital probe launched in 2010 that was redirected from its parking orbit in April to approach Toutatis at the last minute when the asteroid happened to come close to Earth. The two are very different types of missions.

Do you have a point? Because it sounds like you're fishing (somewhat desperately) for a rather far-fetched doom-scenario just to get a chance to call China irresponsible.
Guess what, asteroids don't make any sudden movements, so there isn't any real danger of crashing into it unless you're completely incompetent, which the Chinese are not (despite many slashdotters baseless assertions to the contrary). Besides, it's a 50000000000000 kg rock, a collision with a small probe won't even make it blink.

Chang'E's flyby of 4179 Toutatis is certainly an impressive feat. But, given that Hayabusa took samples while several meters above the surface of 25143 Itokawa, and that NEAR-Shoemaker actually landed on 433 Eros, I don't see how the term "closest" (which the article uses as well as the summary) can apply. Unless they mean "the asteroid flyby mission that took place nearest to Earth," which, while interesting, doesn't seem to be how this is being presented.

Some of the source articles from which Gizmag stole this story referred to this being the closest flyby of this particular asteroid. The wording was such that when I first skimmed one of them even I thought the claim was that this was the closest approach to any asteroid. When I went back and parsed the whole sentence it became much clearer - Gizmag must never have read their sources carefully.

You can't compare the two scenarios.
In a flyby the probe is moving really fast relative to the asteroid. It thus can't produce enough delta-v for a last minute avoidance maneuver. The trajectory is determined well before the encounter. How close you can safely get depends on how accurately you can predict the asteroid path. A few kilometers at close approach with a reasonably low risk of collision is pretty good.
If you enter orbit first the situation is completely different. You can gradually lower the orbi

I realize I should have just said that a flyby and an orbit are two different things, and that the article is therefore correct. Explaining why it is easier to get close to an object when you are orbiting around it than when you are flying past it is irrelevant.
