What about a 2:5 resonance?
Pluto is not a Plutino according to David Jewitt, the astronomer who coined the term. "Plutino" means "little Pluto", and since Pluto is a standard-sized Pluto, it couldn't be a "little Pluto." JoelWest 07:37, 13 Apr 2004 (UTC)
- A reasonable definition of plutino is "a minor planet in 3:2 resonance with Neptune". But perhaps a more useful definition is simply "an object in 3:2 resonance", which (1) bypasses the whole "is Pluto a minor planet?" controversy and (2) allows for economy, so that you can write simply "the plutinos" instead of "the plutinos and Pluto" every time you need to refer to such objects.
- Narrow etymological considerations are not the sole consideration. Consider the fact that Hawaii has interstate highways... ponder that for a moment. If it really mattered, you could propose a name change to "plutowano" or something, by analogy with "cubewano", but most people would just shrug and go on using "plutino". -- Curps 07:47, 14 Apr 2004 (UTC)
I just updated the article List of trans-Neptunian objects, but got confused about that Pluto's satellite Charon was described as a Plutino in this article. I assumed this was in order and just added it as its type there, but I don't really see how it would be one according to the definition (orbit similar to Pluto's -- which it clearly isn't, as it doesn't even orbit Sun, but Pluto).
