What's with the "Several million years later" context in the transcription?!? The distances might be vast and all, but i doubt the timeframe is ''that'' long... -- [[Special:Contributions/173.245.51.210|173.245.51.210]]

::You are discussing editorial elements included in the transcription that have no relationship to the original comic. Regardless of any implied passage of time the comic does not directly state a time-frame that passes and the transcript should only include information contained in the original comic. Any discussion of time-frame should take place in the explanation. The panels imply a pause of unspecific time. The transcript should read the same.

Uhhh, while I observed that close encounter of ISON at the sun yesterday live I was sure Randall would do a comic on this matter. And he did. That's just funny for me. --[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 21:28, 29 November 2013 (UTC)

== When is a comet a comet? ==
  
 
Wikipedia says "A {{w|comet}} is an icy small Solar System body that, when passing close to the Sun, heats up and begins to outgas, displaying a visible atmosphere or coma, and sometimes also a tail."  I see no clear suggestion on Wikipedia that a {{w|small Solar System body}} might change from being an asteroid to being a comet each time it passes by the sun and starts to outgas.  It seems to me that SSSB's that contain ices and other volatiles that would outgas given enough heat are comets, but I haven't seen that question really addressed clearly by any authoritative sources.  For now I'm switching the references to distant comets from "asteroid" to "comet nucleus", which is used on wikipedia and seems like a neutral term for an icy object that would show a cometary atmosphere and tail when close to the sun.  Also, the oort cloud is hypothesized to have both a spherical and a disk-like structure, and is part of the solar system.  Please discuss further related changes here.  Thanks!  [[User:Nealmcb|Nealmcb]] ([[User talk:Nealmcb|talk]]) 16:34, 1 December 2013 (UTC)

:The most false understanding is: A comet is a dirty snowball. In fact it's just a snowy rock, most of it is still rock, otherwise it would break up at a distance between Earth and Venus. And all the frozen gases are not only H<sub>2</sub>O. Furthermore a comet is a comet when we can see its shape, unless that tail is shown it's just a small object at our solar system, not more.--[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 22:17, 1 December 2013 (UTC)
 
::The wikipedia references in the article talk of objects out in the Oort cloud as "comet nuclei".  Unless you can find better sources, that's what we should go with.  [[User:Nealmcb|Nealmcb]] ([[User talk:Nealmcb|talk]]) 14:56, 2 December 2013 (UTC)

Diameter of the sun: 1,391,000 km
 
 
Distance of ISON from sun at perihelion: 1,860,000 km
 
 
ISON went within one sun diameter
 
 
One of the above statements is false. All are in the explanation. --[[User:Zagorath|Zagorath]] ([[User talk:Zagorath|talk]]) 18:37, 2 December 2013 (UTC)

Nothing is false. ISON's distance is from the CENTER of the sun. ISON went within one sun diameter distance from the SURFACE. So ISON went closer than 1.5 diameters from the center. 1,391,000 * 1.5 = 2,086,500 which is more than 1,860,000. --[[Special:Contributions/173.245.63.198|173.245.63.198]] 19:28, 2 December 2013 (UTC)

;A definition for a comet doesn't exist
 
I did mark the comic as incomplete again. We have to explain that there is no real definition for comets.
 
*Look at this really big one: {{w|2060 Chiron}}.
 
*Wiktionary says: "A celestial body consisting mainly of ice, dust and gas in a (usually very eccentric) orbit around the Sun and having a "tail" of matter blown back from it by the solar wind as it approaches the Sun." [https://en.wiktionary.org/wiki/comet]
 
*IAU says: "All other objects (except planets and dwarf planets), except satellites, orbiting the Sun shall be referred to collectively as ''Small Solar-System Bodies''". Look for [http://www.iau.org/public_press/news/detail/iau0603/ RESOLUTION 5A]
 
*And an interesting blog entry at livejournal: [http://suitti.livejournal.com/56460.html?nojs=1 What's the difference between a comet and a planet?]

:Maybe the incomplete tag could be removed again, but this is not my decision because there are maybe still some questions. --[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 22:37, 3 December 2013 (UTC)
 
 
== Memoriam Link is Outdated ==
 
 
The link for "(In Memoriam Comet C/2012 S1 (ISON) Born 4.5 Billion BC, Fragmented Nov 28, 2013, age 4.5-billion yrs old)" currently redirects to a site selling steroids. I'm guessing the domain was stolen.
