Exoplanet naming conventions I'm looking for any exoplanet nomenclature, official, semi-official, proposed, or just a good idea, beyond what can already be found on Wikipedia at

http://en.wikipedia.org/wiki/Exoplanet#Other_naming_systems

Or via the obvious Google searches.

This is a vaguely sci-fi related request.  Lowercase Latin alphabet isn't going to do it once we get out there, and I like the proposal for Greece-roman mythology but there are simply too many planets now, and will be more over time.

As a side issue I'm already familiar with Ian Banks Culture addressing nomenclature, so I accept that humanity being what it is, we can expect about a hundred or so "Vulcan" orbiting various different stars, much as there are 37 "Greenville"s in the USA, currently.

A pointer to a really great fictional idea or naming scheme aside from the schemes mentioned about might be useful.

Interesting technical (non literary) naming schemes beyond the most obvious and trivial ordinal systems could be interesting.
I realise that the following is not a great answer to the question, but was a bit too much to fit into a comment.

The official word on exoplanet naming is

The rules for the scientific designation of an exoplanet are clear and I think will remain so in the published literature for the forseeable future.

However, here is an earnest contribution to the literature which sees the need to change things, especially to cope with planets in multiple star systems.

But perhaps the big news is that the IAU is setting up to allow "popular" names to be given to exoplanets and are running a competition to name a batch. These names will not replace the scientific designations, but will be recognised by the IAU.
