[edit] Requested move
S/2005 P 2 → Nix (moon) – The moon is due to receive the official name of "Nix" tomorrow, in an announcement by the International Astronomical Association. This would normally be an uncontroversial move, but a slightly hasty user created a new page for Nix (moon) separate from S/2005 P 2 which blocks the move of the page together with talk.

- I have fixed any double redirects, but links to the wrong page in articles and templates and the like still need to be updated (preferably by someone who knows these articles well). Ian¹³/t 19:04, 23 June 2006 (UTC)

[edit] name?
The claim's been made that the name of the dog Orthrus, Cerberus' two-headed brother, has been proposed for Pluto II. No refs, but just in case, it's pronounced or'-thrus, Greek Όρθρος. kwami 01:28, 4 November 2005 (UTC)
- I like these names. I made a table of the satellites named. Check this out. — Hurricane Devon (Talk) 13:31, 5 December 2005 (UTC)
This article contradicts itself. In the first paragraph, it says that P2 was discovered in June 2005, but in the accompanying table it gives the discovery date as May 2005. Which is it? 69.168.108.191 06:13, 15 January 2006 (UTC)
- Corrected. The images were taken in May, but the moons in them were not discovered until June. kwami 06:41, 15 January 2006 (UTC)
[edit] Orbit
Man, how the hell do 2 more moons orbit Pluto when Pluto and Charon basically orbit each other? O.o
- Those two moons actually orbit the barycenter of the Pluto-Charon system, rather than Pluto itself. But Pluto being the largest body in the system and orbiting by far the closest from said barycenter, they are considered its moons. — Poulpy 09:36, 2 February 2006 (UTC)
Convention. We could also say that Jupiter isn't a planet, for the same reason. (Jove & Sol orbit each other as well.) Since Pluto is considered to be the "planet" and Charon the "moon", everything is colloquially said to orbit Pluto. kwami 17:58, 2 February 2006 (UTC)
[edit] Article Name Change
Science magazine reports that S/2005 P 2 will be called "Nix". [1] This article should presumably be moved to Nix (moon), but I suppose it is appropriate to wait until the official announcement on June 23.RandomCritic 06:35, 21 June 2006 (UTC)
- No, that's just silly, it's not like it's going to NOT get renamed. The move simply should have been done properly, as a MOVE, not a copy and paste. Now that there's a Nix (moon), though, that's impossible until there's some bureaucratic action here. Blah. --Kaz 02:37, 23 June 2006 (UTC)
[edit] Spelling of Nix
I have read that the spelling "Nix" was used instead of "Nyx" to avoid confusion with 3908_Nyx. Can someone with access to the IAU Circular tell me if it goes into detail on a justification for this? Has use of a nonstandard spelling of a deity's name occurred before? It seems kind of weird to me. You could have names like "Persefonee" and "Titann" and so on. --Cam 01:09, 23 June 2006 (UTC)
- Yeah, it's pretty stupid; but that's about what you can expect from academia, these days. They're no longer expected to even be familiar with, much less understand and respect, classical language, history, or any other such stuff outside of whatever narrow discipline they've chosen for a specialty. --Kaz 02:44, 23 June 2006 (UTC)
- It would seem to set a strange precedent. If I were an astronomer I might try to name a satellite I discovered "Cereeze" or "Vessta" or something, to poke fun at this. --Cam 03:21, 23 June 2006 (UTC)
- I can recall some asteroids, such as Ganymed and Kressida, having their spelling changed like this, to make their names different from the moons - probably this is the first case it is applied viceversa (to a moon, because of an already existing asteroid), but there's nothing new in it. I can't see the reason behind it either, especially because problems arise when you have to translate the names (since I'm from it:Portale:Astronomia): you cannot keep the spelling differences, and both names become Ganimede, Cressida, and Notte in the case of Nix. --Leaden´skij 16:25, 23 June 2006 (UTC)

Whoa, it's simple. The Egyptian version is "Nix". So it wasn't a spelling change, just a pantheon change. So no need to slam academia there. Previous examples with asteroids were done to reflect differences in transliterating Greek. With the main asteroids, it was traditional in German language to transliterate kappa as "k" not "c" as in English. So, thus Kalliope, Klio, Klotho, etc. IN any event, I like an Egyptian name for a moon of the god of the underworld. --Sturmde 21:07, 28 June 2006 (UTC)
- I assume they're talking about the name of Nyx in an Egyptian form of Greek. Same goddess, same pantheon, but a different form of the Greek language, where the name was spelled nu-iota-xi rather than nu-upsilon-xi. I'll have to head to the library and look it up. In the meantime I retract my Persfonee/Vessta rants above. :-D --Cam 23:27, 28 June 2006 (UTC)
- As likely as not to be Coptic. Septentrionalis 15:49, 11 August 2006 (UTC)
- I wouldn't retract the rants. I'm a graduate student who specializes in the Ancient Mediterranean world. I study both Greek and Egyptian. And I HAVE NO IDEA what they're on about here. I really don't think it's a Coptic form: upsilon is normally kept as upsilon in Coptic (though it was probably pronounced more like an eta). --Iustinus 23:45, 23 August 2006 (UTC)
- Interesting, thanks. I think I'll try to write to someone involved with the naming to see if they have a cite or can explain what they mean by "Egyptian." (Whatever I might find out would be original research, though, I guess.) --Cam 01:03, 24 August 2006 (UTC)
- If you find anything, be sure to let me know! --Iustinus 01:24, 25 August 2006 (UTC)
- Well, I wrote to the USGS/WGPSN a year ago seeking a source for the "Egyptian spelling" statement and soon got a friendly reply saying that the question had been forwarded to someone who might be able to answer. Unfortunately I heard nothing further. I hope a source comes to light eventually, I'm still mighty curious about what they meant. --Cam 05:16, 29 September 2007 (UTC)
- Hadn't checked this page since august of 06, but when I come here it's within days of your last update. Funny. Too bad your update is negative. Bah! --Iustinus 07:49, 8 October 2007 (UTC)

Nix is also Latin for snow - don't know if that was intended or not, but it's kind of appropriate. DenisMoskowitz 17:36, 29 June 2006 (UTC)
- Hey Denis, tell your brother Salve for me ;) --Iustinus 23:45, 23 August 2006 (UTC)
[edit] mass
The article's value of <5×1018 kg is extremely bloated. Given the quoted radius of 44 km, Nix would have to have a density 112 times that of water! In case of very low albedo, say 0.05, the corresponding diameter would be 116 km, and its density would still have to be 6 g/cm³. For the assumed value of 0.35 for albedo, and with a likely density of 1.5, Nix's most likely mass is ~7×1016 kg. The largest reasonable values would be with Albedo ~0.05, and density ~2g/cm³, leading to mass < 1.6×1018 kg. Deuar 16:27, 5 July 2006 (UTC)
- The radius is extremely uncertain. Stern el al. 2005 give the upper limit on the radius as 137 km, for example, as does Weaver et al. 2005 WilyD 15:46, 13 July 2006 (UTC)
- There, I fixed up the sidebar with a good cite WilyD 15:59, 13 July 2006 (UTC)
[edit] niks?
What's this italic after the title for? If its just a pronunciation guide, I doubt that any English speaker doesn't know how to pronounce x. Remove it or IPA it, or explain what it's for. 219.77.98.166 03:34, 18 September 2006 (UTC)
[edit] S/2005 P2 redirection
S/2005 P2 redirects to Pluto instead of here. Can someone fix that please (I don't know how)
