767:. All of my comments and concerns have been addressed, and I believe this article is comparable to the rest of the solar system FAs. Excellent work by everyone involved. The prose is clear and concise, with only a minimum of necessary technical jargon. Even to me, someone with limited astronomical experience, it's understandable. Great work.

coverage of the L4 and L5 clouds, perhaps due to their placement with respect to the Milky Way, making the detection of faint
Trojans more difficult in one cloud than in the other. A careful experiment to determine N4/N5 free of the effects of observational bias has yet to be reported and is urgently needed.
955:
My one issue is regarding the statement about, "this disparity is probably due to observational bias from their respective positions relative to the Milky Way." Intuitively I'd expect the
Lagrange points to spend equal amounts of time along the line of sight to the galactic plane, so this leaves me a
1070:
Apparently this claim about the Milky Way background originates with
Shoemaker '89 (so sayeth Freistetter), Freistetter then claims that this should've been resolveable by now, and Freistetter definitely isn't claiming his answer is correct. He lists 5 different possible causes, three of which he
1093:{de-indent} It sounds like this will require a consensus decision to resolve, but I don't expect the result will effect the article quality. As my concern WRT the FA status was satisfied, I've changed my preference to support. Thank you for putting together another high quality astronomy article!—
285:
You mention that no
Lagrange asteroid was found until more than a century after Lagrange's hypothesis. Was a Trojan asteroid the first of these found? If so, I'd suggest explicitly writing that. If not, then I'd suggest removing that last sentence of the first paragraph of Observational History
1007:
Indeed, that is a perplexing statement, but if Jewitt claims as much, it is probably true. The only guess I can make is that the limiting survey(s) were arranged in time such that this is the case (e. g. if the survey that determines the limit was
January 23rd 1995 - February 17th, 1995, the

Given that the best characterized (brightest) Trojans show the smallest deviations of N4/N5 from unity, it is reasonable to suppose that the larger values of this ratio are produced by observational bias in favor of one cloud over the other. Such a bias could result from unequal observational
889:- which is where I get asteroid/comet/KBO orbital data from (the same data is published in other places though). Jupiter's J2000 orbital elements are from Murray and Dermott's Solar System Dynamics, which was published in 1999 by the Cambridge University Press. Cheers,
807:(Turns out the date was for the letters, not the image.) If this was taken at the turn of the century and the photographer was 20–30 years old then, he might only have passed away 40 years ago; thus the image is very likely to be still copyrighted in Germany.

In the graphic of Earth's
Lagrange points, are Jupiter's different in any way? If so, I'd suggest stating that they're similar in the caption. Otherwise, you don't draw any direct connection between the subject and the
209:— I gave the article a quick copy edit and was pleasantly surprised at its quality. I'm not an expert in astronomy by any means, but it's excellent work as far as I could tell. I did have a few questions, however:

I'd strongly suggest eliminating ambiguous terms such as "very small" and the like. I killed quite a few in the copy edit, but you might want to take another look to see if I missed any.

I am nominating this for featured article because the article is about a significant population of objects of the Solar System and, in my opinion, is ready to become a featured article.
1026:
which (to me anyway) appears to indicate there may be more to the discrepancy than observational bias. But I don't have full access to this paper; just the abstract. Thanks.—
484:
And as a final question, do these have any connection to Comet
Shoemaker-Levy 9? If so, it might be worth mentioning simply because of the well-known nature of that comet.

I am not sure this is really the right approach. Jewitt may well be the authority on minor planets these days, ignoring his statement seems like a misstep.
380:. That's something that probably should have an article of its own, based simply from the way you used it. Don't feel as if you need to stub it out, though.

In the nomenclature section, wouldn't it be better to use the names of the asteroids (including the number) rather than just the names of the people?

When talking about horseshoe orbits, how do we know that they can follow these orbits without having observed it? Is it mathematically derived?

There is no connection, as that comet originated in the Kuiper belt, not among

The only way to do that is to remove the margins of error, which leads to a less exact but more readable figure.
