Talk:Plutino
From Wikipedia, the free encyclopedia
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)
On the other hand, you don't have to have a big Gian and a little Gian to call Gian "Gianino." Pluto is little, and it is Pluto. "Plutino" could just be an affectionate diminuitive. --Chronodm 23:17, 1 November 2005 (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).

Plutino most likely is going to be redefined as a 200yr orbit planet by the IAU. This article should refect that discussion. see talk:planet talk:pluto talk:ceres Hopquick 15:08, 16 August 2006 (UTC)
- You're thinking of Plutons, not Plutinos. DenisMoskowitz 15:25, 16 August 2006 (UTC)

[edit] Orbital period
Should the article contain some mention of the fact that Plutinos all have orbital periods around 247.5 years? The fact that they'd all have similar periods would be implied by the fact that they're in resonance, but might it be good to mention the approximate period just so the reader doesn't have to chase off to the Neptune article and multiply by 1.5, or into one of the individual plutino articles to find the period?

- Good idea. Deuar 09:28, 25 August 2006 (UTC)
[edit] Plutino
Excuse me, but "plutino" means "little Pluto". How can Pluto itself be a little Pluto? 209.247.22.199 00:43, 26 December 2006 (UTC)
