further questions[edit]

How fast do the particles move on the orbit?

They orbit very quickly, its quite remarkable. —Preceding unsigned comment added by 69.139.10.172 (talk) 00:31, 13 August 2009 (UTC)[reply]

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..


This page should also have some details of which countries can view the shower as well fireryone —Preceding unsigned comment added by 124.186.193.119 (talk) 05:59, 12 August 2009 (UTC)[reply]

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)[reply]

Not too good...[edit]

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!"

article as section[edit]

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

(They are only meteorites after they hit the ground - until then they are meteors. Best viewing of meteorites is probably in a museum someplace.) SteveBaker (talk) 00:12, 22 August 2008 (UTC)[reply]

plane crash 8/12/2009[edit]

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 :( 76.16.183.158 (talk) 10:22, 12 August 2009 (UTC)[reply]

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)[reply]
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)[reply]

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 67.174.130.47 (talk) 23:12, 12 August 2009 (UTC)[reply]

When and where to see it[edit]

I live in New York City, where can I view it and what time should I view it at? —Preceding unsigned comment added by 70.23.221.60 (talk) 13:36, 12 August 2009 (UTC)[reply]

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)[reply]
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)

Filament link is ridiculous[edit]

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.

DerekTK (talk) 18:14, 13 August 2009 (UTC)[reply]

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)[reply]
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.  Chzz  ►  05:32, 12 March 2010 (UTC)[reply]

Update?[edit]

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??? 71.108.104.221 (talk) 19:16, 18 July 2010 (UTC)[reply]


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 82.52.44.61 (talk) 17:57, 12 August 2010 (UTC)[reply]

VANDALISM[edit]

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.

someone please fix! —Preceding unsigned comment added by 70.121.217.22 (talk) 03:14, 13 August 2010 (UTC)[reply]

Peak of shower is on 12th of August - but in which time zone?[edit]

Can we get a more accurate time here, with hours of the day and time zone perhaps? Also, is the peak different or the same around the world? --93.223.44.237 (talk) 11:19, 4 August 2011 (UTC)[reply]

Google featured this on their homepage today. FYI, Charles Edwin Shipp (talk) 18:03, 12 August 2014 (UTC)[reply]

Reason for early morning best viewing?[edit]

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?

More rain hits the front windshield of a moving car then the side windows or back window. (Meteors generate their own light and it has nothing to do with reflected sunlight.) -- Kheider (talk) 20:06, 18 October 2012 (UTC)[reply]
Right - I believe the reason is that your part of the Earth is running into the dust particles in the pre-dawn hours. Bubba73 You talkin' to me? 06:25, 2 June 2015 (UTC)[reply]

This reader believes that the radiant is near the zenith at dawn at our latitude, therefore the particles fall vertically into the dense atmosphere at about dawn-time, and the ZHR realizes. The windshield effect goes as follows: Actually the Perseides fall orthogonally (63 degrees front including gravitation) to the earth trajectory, like the rain drops fall orthogonally (90 degrees front) to the vehicle direction. This causes them travel fast, they impact heavily, because the relative direction is onto the car, respectively the earth. The direction of the particles, that is the configuration of the particles, is however not related to the time of day. The particles traverse the earth atmosphere all time with the same entry speed, as - one could imagine - rain drops hit an open car everywhere, but depending on the angle of the wind shield, they splash better or not at all.77.59.144.68 (talk) 23:52, 21 July 2015 (UTC)[reply]

About S. Lawrence[edit]

Restored hypothesis of modified dates of death. The first written testimony dates back to 100 years later in this paper. https://it.wikipedia.org/wiki/Depositio_martyrum Across Italy where there were temples to Priapus and LaRenta they were built churches consecrated to Lorenzo. This hypothesis is documented in the document of Castrum Inui. The improbable event is the overlapping of the Priapo's festival with the martyrdom of the saint, not his canonization on a pre-existing festival that is rather a phenomenon well documented. The Depositio Martyrum fixed events to give unity to the church, he had no historical claims more than it has today a papal encyclical. The Catholic Church has abolished a section of the underworld (limbo) has no problems to secure the death of a saint at the table. — Preceding unsigned comment added by 82.53.139.245 (talk) 12:35, 26 October 2015 (UTC)[reply]

Further further questions[edit]

What size are the particles burning in the atmosphere?

What is their composition?

Can they damage satelites or the ISS?

How come they are not recessing into to the sun if they are bound in an oval trajectory with only one center of movement (focal point)?
