I've had a bash at creating an image showing a 'family tree' of how the Kreutz group's major members have come to exist. I think a nicely-done graphic could really illustrate the article well, but I'm not sure what I've done is very good at all, so thought I would put it here first. Would appreciate comments, and if anyone can design a better-looking diagram that would be great! Worldtraveller 02:15, 25 Mar 2005 (UTC)
The images in particular, both of the sungrazer and the family tree above, make my heart sing. +sj + 05:56, 28 Mar 2005 (UTC)
Does anyone have any info on the aphelion or eccentricity of these comets? Google doesn't seem to know. -- Doradus July 6, 2005 04:07 (UTC)
I was confused by this section... "This comet was found to have passed just 200,000 km (0.0013 AU) above the sun's surface, equivalent to about half the distance between the Earth and the Moon. It thus became the first known sungrazing comet. Its perihelion distance was just 1.3 solar radii. "
Isn't perihelion the point of closest approach to the sun? How can that distance be both half the distance between Earth and Moon, and 1.3 solar radii? I must be reading it wrong... can someone clarify? Wordie 9 July 2005 04:14 (UTC)
I've recalculated the numbers in the section describing the brightness of the Sun as seen from a sungrazer - here's my thinking:
Does that make sense? Worldtraveller 09:29, 18 August 2005 (UTC)
I randomly stumbled on this article while perusing a list of articles with "Great" in the name and arriving here from Great Comet of 1882. Really nice introduction to something I hadn't heard of before. Carcharoth 15:02, 20 January 2007 (UTC)
Per the Great Comet of 1882 article as cited there:
I think this article needs to be updated to reflect this modern opinion. The diagram of the family tree would need to be updated.

The audio link on the pronunciation of Kreutz actually links to the word "sungrazers". Rsduhamel ( talk) 20:07, 9 July 2009 (UTC)

This 2005 WP:FA promotion was last reviewed in 2008 and has not been maintained to WP:WIAFA standard. Unless these issues can be addressed, the article should be submitted for a Featured article review:

From the article on may 13, 2022: "The first comet whose orbit had been found to take it extremely close to the Sun was the Great Comet of 1680. This comet was found to have passed just 200,000 km (0.0013 AU) above the Sun's surface, equivalent to around a seventh of Sun's diameter, or about half the distance between the Earth and the Moon. It thus became the first known sungrazing comet. Its perihelion distance was just 1.3 solar radii." 1.3 radius of a sphere is 0.65 of a diameter. 1/7 of a diameter is 0.14 of a diameter or 0.29 of a radius. Rich ( talk) 19:40, 13 May 2022 (UTC)
Does anyone have a source for this addition? Jo-Jo Eumerus ( talk) 07:42, 15 November 2023 (UTC)
This serendipitous event happened when the Eclipse Comet of 1882 reached its perihelion just as a total solar eclipse took place. The celestial alignment allowed observers to notice the comet against the darkened backdrop of the eclipse. This rare occurrence provided a unique opportunity for astronomers to identify and study the comet, which otherwise would have remained undetected due to its close proximity to the Sun during that period of the year.I find it plausible, but sans source it can't stay.
