For a comet to become spectacular, it also should pass close to the earth and be visible to casual observers. Halley's Comet, for example, is usually very bright when it passes through the inner solar system every 76 years, but during its 1986 apparition, its closest approach to earth was almost the most distant possible. The comet became visible to the naked eye, but was definitely unspectacular.
I'm not surprised the 1976 appearance was not spectacular; especially since it came not in 1976 but 1986! — Preceding unsigned comment added by 130.76.96.17 (talk • contribs) 17:49, 17 January 2005 (UTC)
Capitalisation
Great comet or Great Comet? The article is inconsistent on capitalisation at the moment, but I don't know enough to decide which is right. Markyour words 18:50, 4 February 2006 (UTC)
Is comet C/2006 P1 (McNaught) great?
This comet is very similar with comet West. It can be included in this article. What do you think? 195.189.142.220 18:47, 10 January 2007 (UTC)
- It's pushing the definition. Yes it's bright, but viewing is impaired by close proximity to the Sun and very small size. Observing it on Mt Soledad on 12 JAN, very few people could see it even when pointed out to them. Most prople were there to watch the sunset and were not aware there was a comet visible. Rereading the main article, it may not fit the description as defined. Exaggeration could lead to future disappointment, something that has happened repeatedly with astronomical objects in the past.

Other great comets
According to this, comet
- Ok, so should I create an article for the Southern Comet as I have done with articles for many other comets? Thanks. ~U) 22:28, 10 December 2007 (UTC)]
Given that it was one of two impressive (though not really Great) December comets only a year apart, I don't see why not. -- Kheider (talk) 23:31, 10 December 2007 (UTC)
Everyone needs to keep in mind that a comet can be very bright without being considered a "Great Comet" - it needs to be both bright AND far enough away from the sun (in terms of angular degrees) to also APPEAR bright. A comet could be at magnitude -5 (spectacularly bright)but only a few degrees away from the sun when that bright, and hence never achieve a spectacular appearance in the night sky.12.77.139.157 (talk) 01:04, 14 March 2010 (UTC) veteran astronomer
Comet Holmes?
Has
Not a Great Comet in my book, but it is an interesting one because it was the second time it experienced an outburst. Choronzon (talk) 23:01, 26 July 2010 (UTC)
Comet Seki-Lines (1962)
First time I see that comet mentioned in a list of Great Comets. It was a bright comet but definitely not "Great Comet" material in my view. Google comes back with roughly 120 results in images for seki-lines compared with ikeya-seki with 3210 Choronzon (talk) 23:01, 26 July 2010 (UTC)
Brainstorm
Just for brainstorming Great Comets on comets-ml. (Hale-Bopp vs Hyakutake) -- Kheider (talk) 15:35, 24 December 2011 (UTC)
- I've included Lovejoy in the list of Great Comets. SOHO's website and some US Military sites called it the "Great Birthday Comet of 2011". ~AH1 (discuss!) 21:27, 25 December 2011 (UTC)
Next great comet?
Would it make sense to add a short note about
- Not really since there is currently too much hype and not enough facts about the brightening trend for the comet. Comets often behave differently when they are within 1.5AU of the Sun and comet ISON will not be 1.5AU from the Sun until October 2013. Comet Elenin could have been a great comet if it did not disintegrate when it was ~0.8AU from the Sun in August 2011. -- Kheider (talk) 17:19, 12 January 2013 (UTC)]

- Support: This is not a proper name, it's just a generic categorization like marine mammal or metropolitan area. — SMcCandlish ☺ ☏ ¢ ≽ʌⱷ҅ᴥⱷʌ≼ 01:11, 13 September 2014 (UTC)]
Support. "A Great Comet is a comet that becomes exceptionally bright," according to the opening. I am skeptical of the validity of this concept. But irregardless, we can still capitalize it correctly. Clodhopper Deluxe (talk) 01:49, 13 September 2014 (UTC)Wikipedia:Sockpuppet investigations/Kauffner- It's not a hard scientific category, as far as I can tell, but it definitely is a thing culturally and so on. —innotata 20:49, 13 September 2014 (UTC)
- Support the concept of a "great comet" is separate from the event of a Great Comet. The individual events would be proper nouns, but the general class is not. -- 70.51.46.146 (talk) 05:09, 13 September 2014 (UTC)
- Support as pointed out by 70.51.46.146, yes, individual "Great Comets" should have their names capitalised, but not—in this case—the generic term. —innotata 20:49, 13 September 2014 (UTC)

C/2020 F3 (NEOWISE)
If the definition for a "great comet" is simply a comet that's bright enough to be noticed by casual observers who aren't purposefully looking for it, then I think NEOWISE definitely fits the bill. — Preceding unsigned comment added by Kdenny994 (talk • contribs) 16:41, 11 July 2020 (UTC)
- It is needs to be exceptionally bright and generally for an extended period. Too many people confuse "damn good" for greatness. How it performs in the evening sky will also be important. A large outburst in the evening sky would definitely help the case. But NEOWISE might simply be passing too far from Earth (100 million km) to achieve true greatness. -- Kheider (talk) 01:36, 12 July 2020 (UTC)
In that case, I suggest amending the definition of "great comet" to reflect that. As it currently stands, based on that definition, Lovejoy (2011) and NEOWISE fit the current definition. -- Kdenny994 (talk) 15:07, 12 July 2020 (UTC)
- Neither Lovejoy or NEOWISE are the best of the best. I also do not see reliable sources specifically calling them a "great comet". Lovejoy was called a great Christmas comet, but that was more a play on words. Eddie Irizarry actually says NEOWISE is not great. If a comet is truly a "great comet" there should be astronomers calling it such. -- Kheider (talk) 15:34, 12 July 2020 (UTC)
- There are astronomers that call NEOWISE a great comet: How Great of a CO+CO2 producer was The Great Comet of 2020? The survey also discovered the Great Comet of 2020, garnering public attention from across the globe. C/2020 F3 (NEOWISE) was discovered (...) and has become the Great Comet of 2020. Owing to these parameters, this comet has been qualified as a “great comet” by some researchers. [2] C messier (talk) 20:24, 26 February 2023 (UTC)
True, but I'm not making the argument that Lovejoy and NEOWISE are "great comets". I'm raising objection to the definition on this page, "which are bright enough to be noticed by casual observers who are not looking for them, and become well known outside the astronomical community." Lovejoy and NEOWISE both meet this definition. -- Kdenny994 (talk) 11:24, 13 July 2020 (UTC)
- In this day and age of social media, I am not sure what "well known" means as it is a vague term. How many non-astronomers will remember NEOWISE in 6 months? -- Kheider (talk) 12:44, 18 July 2020 (UTC)
Probably quite a few. At this point, NEOWISE is likely the most photographed comet in history. Even amateurs with a cellphone can photograph it! -- Kdenny994 (talk) 21:25, 20 July 2020 (UTC)
- Certainly not forgotten, it has become a reference point for an easy to spot comet: "This comet isn't expected to be quite the spectacle that Comet NEOWISE was back in 2020," NASA said. Will it be another comet NEOWISE ? Probably not. --C messier (talk) 20:37, 26 February 2023 (UTC)
Comet Lovejoy
Comet Lovejoy (C/2011 W3) was largely invisible to the naked eye during its peak brightness due to its proximity to the Sun. Do reliable sources truly consider it a "Great Comet"? Seems dubious to me. -- Kheider (talk) 09:26, 12 July 2020 (UTC)
