Titan nomenclature[edit]

The main article previously claimed that features on Titan would be named after "ancient displaced cultures". However, the USGS planetary nomenclature page changed sometime between 2003 Dec 7 [1] and 2004 Feb 13 [2]. -- JTN 13:09, 2005 Jan 19 (UTC)

Languages[edit]

I'm confused - if the IAU only gives a single name to each object, why do the planets have different names in French from English (e.g. Saturne versus Saturn)? Is this purely for historical reasons? In such cases, are both names official or only the English, or only the French, or Latin? -86.140.131.33 19:35, 17 August 2006 (UTC)

On a related point, if there's a new class of objects called plutons, will the French (and others) have to stop calling Charon's companion Pluton? —Tamfang 00:18, 18 August 2006 (UTC)

Stellar Notation[edit]

Sun = Sol
Mercury = Sol-1
Venus = Sol-2
Earth = Sol-3 -or- Sol-T-1
Mars = Sol-4
Jupiter = Sol-Prime
Saturn = Sol-5
Uranus = Sol-6
Neptune = Sol-7
Pluto = Sol-D-1 (While not a planet) -or- Sol-T-2 (While a planet)
Eris = Sol-D-2

Confusing[edit]

Hi. In the section "IAU rules and conventions", number 2 says: " 2. Features with longest sides below are not assigned official names unless they have exceptional scientific interest.". Am I missing something, or is this unclear? Below what? Longest sides of what? Davidelit (talk) 06:56, 13 January 2009 (UTC)

Roadrunner would probably know. Now if only getting hold of him wasn't as hard as it is for Wile E. Coyote... I assume it's referring to the longest side of a feature like the Mares on the moon, or Mons Olympus of Mars. What's the shortest the longest side can be, though?

itty-bitty features[edit]

A curious recent change:

Features with longest dimensions below 100 metres ....

became

Features with longest sides below <!-- missing number? --> ....

(Emphasis added.) What is the longest side of a round crater? I'm reverting; http://planetarynames.wr.usgs.gov/rules.html says "features whose longest dimensions are less than 100 meters". —Tamfang (talk) 18:49, 13 May 2010 (UTC)

Koulouris links[edit]

I've deleted these several times from various articles, although User:JKoulouris "WOULD APPRECIATE IF THIS WOULD NOT BE REMOVED". Just this once I'll politely ask the collective whether I've overlooked some reason to keep them. —Tamfang (talk) 19:20, 22 June 2011 (UTC)
