How fast do the particles move on the orbit?
How fast does the dust from 1862 spread over the orbit? If it didn't spread all of the orbit yet: Where the max?
One could calculate if one knew the period of the orbit. Probably it's about the same as that of the comet?
I don't yet get how this spreading over the orbit works. Should that be very very slow, because a fast spreading would mean changing the velocity relative to the comet and that means leaving the orbit?

question from an Australian reader: do you mean pre-dawn in America, or pre-dawn GMT, or pre-dawn in which part of the world???
- It's the same everywhere. The meteorites don't care what's on the surface..
- Since this is the trail of a comet that has spread out and filled the entire highly elliptical orbit, shouldn't the Earth pass through that orbit twice in each year? The Earth's slightly elliptical orbit along the ecliptic should intersect with any other ellipse at two points, as long as the comet's orbit is on the ecliptic plane. Is the comet on the ecliptic, or is it not. If not, perhaps only one point intersects with the Earth orbit. --Richard Arthur Norton (1958- ) (talk) 06:44, 12 August 2009 (UTC)
Not too good...
This looks nothing like an encyclopedia article... and as much as I'd like to fix it I have no idea how to edit this site...
I agree. It's obviously well-intentioned but the tone is an embarrassment here, reading much more like friendly advice for kids from Aunt Blabby than an encyclopedic article with objective knowledge for adults. EXAMPLE: "For the most pleasant viewing experience, find a spot far from any city lights. ...Bring a reclining chair so that you can view high in the sky in comfort; there's no point in filling half your field of view with trees. Don't forget warm, mosquito-proof clothes or, better, a sleeping bag. No matter how hot the days are, it can get surprisingly chilly under a clear sky late at night, especially when you're inactive. And for many people, the most important accessory is bug spray for the parts of you that remain exposed!"

Much of the present article would make a great section titled "Viewing the Perseid metorites". SmithBlue 12:31, 12 August 2007 (UTC)

- I don't think it's very useful so I'd say do not add. I find it useful to have here in the discussion though as it explain the possible peak in views and edits for the page. Mverleg (talk) 22:57, 11 August 2009 (UTC)

plane crash 8/12/2009
What is the probability when every minute meteor fail down on radius 10-20 km, the visible horizon (a cone up), to hit an airplane ? That I can calculate (sky surface/airplane surface * number of hits in the sky surface/time * time of flight duration) But what fraction of meteor come down to 12 km altitude? Is the Earth hit the meteors circling sun or the meteors hit the earth. I think it is sum of both velocities. Do you know about any statistical calculations? Can pilot outmaneuver seeing approaching meteor (assuming at night)(are pilots train to look up (airbus cameras)) --- Anyway plane crashed and was piloted by "experienced pilots". I need quick answer since gonna flight tomorrow to Europe and this is day nr 13 and flight is at nigh arrival at morning :( 22.214.171.124 (talk) 10:22, 12 August 2009 (UTC)
- This page is for discussion of the Perseids wiki entry. Reprinted AP releases don't appear to be relevant. Eedlee (talk) 14:20, 12 August 2009 (UTC)
- note, virtually all Perseid meteors are grains of sand or smaller, so they would certaintly not damage an aircraft. The probability of a dangerous meteor hitting an aircraft remains extremely low, and not effected. Also, the typical Perseids you see burn up in the upper atmosphere, i'm pretty sure its well above where commercial airlines fly. So don't worry!Danski14(talk) 15:42, 12 August 2009 (UTC)
I realized that since IS station is not endangered that the risk is virtualy nill, but is alredy to late ... (few hundred $ reshedule) There is also error in sky surface calkulation radius calculation at least 1e+4 . Nad th plane surface is > 200 m^2 126.96.36.199 (talk) 23:12, 12 August 2009 (UTC)
When and where to see it
- Get somewhere away from city lights as best you can. Since they are dim, you at least want to be able to adapt your eyes, even if you can't get away from the light pollution. The best times are after midnight, and getting better as it gets closer to dawn. The constellation Perseus will be rising in the East. You may want to face the East for perspective, but they can appear anywhere in the sky. Don't go with high expectations, its not a huge one this year and with all the lights it may be one every few minutes or less. Danski14(talk) 15:47, 12 August 2009 (UTC)
- Note, this page is for discussing improvements. If anyone else has general questions, its best to consult the article, or go to the Reference Desk. 15:50, 12 August 2009 (UTC)
I'd edit this myself but I can't due to the current semi-protection. In the opening paragraph of the article, a recent filament left behind by the comet is mentioned, but the word links to the "filament" article regarding the overall structure of the universe. This is obviously ridiculous and should be corrected.
- I don't know what it should link to, but I changed it to the disambig page Filament so it won't be inaccurate. ~ Booya Bazooka 05:07, 14 August 2009 (UTC)
- After some digging, I'm pretty sure that the source of the word is this NASA site. I've added the reference, and I removed the wikilink from filament altogether; I think they're just using the word to mean "a thin thread", and the disambig page didn't seem to help with that. I suppose we could link to wiktionary or something, but that seems a bit over the top. 05:32, 12 March 2010 (UTC)
This article still talks about the 2009 shower as if it is going to happen. Can someone knowledgeable update this with information about the 2010 shower??? 188.8.131.52 (talk) 19:16, 18 July 2010 (UTC)
Higly Important! Please, check the 2010 Pick Shower. NASA reports the pick to be among 12-13 August (today...) whereas this article states 23-24 August. Source of information: http://www.nasa.gov/connect/chat/perseids_2010.html Cite: "This year's Perseid meteor shower peaks on Aug. 12-13, and it promises to be one of the best displays of the year." —Preceding unsigned comment added by 184.108.40.206 (talk) 17:57, 12 August 2010 (UTC)
I can't figure out how to get to the talk page for it, but the mobile version of this site has been vandalized. The URL is http://en.m.wikipedia.org/wiki/Perseids?wasRedirected=true and contains the following sentence:
The Perseids are so-called because the point they appear to come money grubbing jews called the radiant, lies in the constellation Perseus.
Peak of shower is on 12th of August - but in which time zone?

Reason for early morning best viewing?
The article says " As with all meteor showers, the rate is greatest in the pre-dawn hours, since the side of the Earth nearest to turning into the sun scoops up more meteors as the Earth moves through space."
I don't think the turning Earth "scoops up more meteors" in the pre-dawn hours. Every time zone has the same optimum viewing ("early morning"), but this accompanies a continuously changing "side of the Earth". Isn't the reason more to do with high altitude reflection of sunlight and an optimum in early morning?
