Name of this article[edit]

According to naming conventions, this star as an accepted common name (Alnitak) as well as, obviously, Zeta Orionis. The name should be under which is more widely used.

  • WRT Google hits:
  • Alnitak + star = 17700
  • "Zeta Orionis" + star = 4910

On google scholar,

  • "Zeta Orionis" + star = 69
  • Alnitak + star = 87

Therefore it would appear Alnitak is the more commonly used name. cheers, Casliber (talk · contribs) 02:04, 13 December 2007 (UTC)

Agreed. Requested a technical move of this page. Metebelis (talk) 23:39, 25 March 2012 (UTC)

The passage "the Alnitak system was found to be almost twice as close" is not at all well written; "half as distant" would be a better way to phrase it assuming that is what was actually meant. - (talk) 12:26, 21 June 2010 (UTC)

Distance: 700 or 800 LY?[edit]

The article switches at least twice between 700 and 800 light years distance. We should pick one, preferably with a recent citation, and stick with it. Any thoughts?

This? XMM-Newton observations of ζ Orionis (O9.7 Ib), 251 parsec, 800 l.y. and more, I think.. --Kirk39 (talk) 09:58, 27 March 2012 (UTC)
Validation of the new Hipparcos reduction (2007) gives parallax = 4.43mas, distance = 225pc = 736ly. The distance in the XMM-Newton paper comes from the older, original Hipparcos reduction (parallax = 3.99mas). I will update the article using the newer data and make it consistent.

Luminosity and temperature[edit]

Why does the infobox give three different luminosities, and three temperatures (two of which are the same) for this star? Bazonka (talk) 06:40, 7 August 2015 (UTC)
