Speculative Theory[edit]

I just removed a dead link from the Peshtigo Fire article that referred to a Discovery Channel story about the comet breakup. Royalbroil 05:41, 10 June 2006 (UTC)[reply]

Possible identification[edit]

Could the one sentence be expanded and given a 'standard' cite reference? Awolf002 21:32, 25 October 2006 (UTC)[reply]

Are you refering to the comment that P/2001 J1 might be part of Comet Beila? Or the comment about the two visible parts of Biela being 1.5 million miles apart in 1852? (I am fairly new to wiki so I am still learning what Wiki considers a standard cite reference. Since the book is from 1886 I might even be able to scane the relevant page.)

Yes, I'm talking about the P/2001 J1 piece. Can this have more detail, maybe to the point of a "subsection"? Awolf002 01:50, 26 October 2006 (UTC)[reply]

In non-astronautics stuff[edit]

[1] Goiás' shield uses this comet in his right side... Citation can be found (in portuguese) in the Catholic University of Goiás' website at [2].

3D?[edit]

One understands why Biela, but what does the 3D mean? —Tamfang 01:51, 16 April 2007 (UTC)[reply]

Comet Halley is known as 1P/Halley since it is the first confirmed periodic comet. Biela is labeled "3D" (instead of 3P) because it was the 3rd confirmed comet and has disintegrated or been lost. Comet 5D/Brorsen is another lost comet. -- Kheider 01:30, 22 September 2007 (UTC)[reply]

Thank you, now I can sleep. —Tamfang 02:02, 22 September 2007 (UTC)[reply]

Importance in scientific history of luminiferous aether[edit]

This section has an interesting point. The luminiferous aether was discredited by the Michelson-Morley experiment, and replaced with Special Relativity. It occurs to me that the very slight anomalies of Mercury's orbit have been deemed to confirm the General Theory of Relativity's digression from Newtonian Solar System mechanics. Is there any possibility of attempting to match these cometary observations with that? DaveyHume (talk) 17:44, 14 October 2015 (UTC)[reply]

With perihelion (q) 0.87 AU from the Sun, Special Relativity is not important to the orbit of Biela's Comet. -- Kheider (talk) 18:10, 14 October 2015 (UTC)[reply]

Maury was not the first to notice the split[edit]

"On 29th December, 1845, however, Bradley and Herrick of Yale University seem to have made the first announcement that Biela's Comet appeared to display a companion. This was followed by the same observation made by Lt. Mathew F. Maury, the first director of the newly founded Naval Observatory in Washington."
