Betel juice[edit]

Any relation between the names Betelgeuse and the English name of Betel juice or is this wholly a coincidence? Schissel | Sound the Note! 16:54, 26 November 2017 (UTC)

How do you mean? Strictly speaking no, but since the movie people have pronounced it more like "Beetle juice" I guess...Cas Liber (talk · contribs) 19:14, 26 November 2017 (UTC)
Since the name 'Betelgeuse' comes from a corrupted Arabic phrase referring to a hand the answer is clearly No. Skeptic2 (talk) 21:35, 26 November 2017 (UTC)

950-1,200 R[edit]

@Lithopsian: As the 1,200 R is obsolete and is also the least reliable estimate, is the 950-1,200 R for Betelgeuse even obsolete? I think so, due to the similar number/upper estimate. ZaperaWiki44(/Contribs) 14:05, 28 November 2017 (UTC)

Scrap it, except as a purely historical and refuted idea. This is why pop-science websites make terrible sources. One brief paper suggests, on the basis of somewhat inconsistent measurements, that Betelgeuse is shrinking and a hundred stories appear on the internet (or one story appears a hundred times with a couple of words changed to make it look different). When those measurements are refuted and explained away (Ohnaka et al 2011, Montargues et al 2014 and Ohnaka 2014), nothing. The number 1,200 didn't even appear in Townes et al 2009, it is a synthesis of angular measurements from 15 years earlier that are no longer considered reliable with a later distance measurement which is also now obsolete. Of course the other two given radii also use 197 pc as the distance, rather than the more recent 222 pc. Betelgeuse could be bigger than we say! Don't go calculating it for yourself though ;) Lithopsian (talk) 17:11, 28 November 2017 (UTC)


Is it pronounced "beetle-juice"? If so, can we indicate that at the beginning of the article, because I think a lot of people are not quite sure how to pronounce the name. Invertzoo (talk) 13:06, 27 April 2018 (UTC)

That is one possible pronunciation, but there at least two or three others. Three pronunciations are given in the starbox, one not cited, and at least one common one missing. Might have to put my editing hat on unless some IPAC-expert gets there first. Lithopsian (talk) 20:04, 27 April 2018 (UTC)

Orbital companions to Betelgeuse - a question[edit]

Hi everyone, just a quick question here. Is the following strange or self-contradictory? In Observation section, the Star System subsection begins, "Various catalogues list up to nine faint visual companions to Betelgeuse." Yet further down, in the Physical Characteristics section, the Mass subsection begins, "Betelgeuse has no known orbital companions." My reading of this leave me thinking there are either zero, or up to nine, orbital companions to the star. The Interloafer (talk) 15:33, 27 January 2019 (UTC)

No contradiction, visual companions are not the same as orbital companions. However, referring to "visual companions" in a section called "star system" is just plain misleading. Lithopsian (talk) 15:43, 27 January 2019 (UTC)
Yeah just looking at that now. I have slotted into observation as it fits better there. Cas Liber (talk · contribs) 18:10, 27 January 2019 (UTC)
