Simulations seem to match  Smiley
In rotating frame the librating period is about 46000y .  
Pluto is represented in grey .

Can we do one for Twotino (119979) 2002 WC19?

Bingo again for the resonance ...
Kevin , I saw you posted the animated version for this asteroid .  
Is it however possible to provide a link to the still image Tony posted , as I think this image gives an overal picture of the motion ?  
I'll post the 2:1 resonance of 2002WC19 soon ...Bingo again .

2002WC19 indeed has a nice 2:1 resonance to Neptune .  
The libration period is about 20000 years as can be seen in the animation .

2060 Chiron
Reply #19 - 03/16/09 at 21:06:35
 
Any signs that 2060 Chiron has a temporary libration around the 3:5 resonance with Saturn, but with say a long-term fluctuation that tends to bring the motion more under the influence of of the stronger 2:3 resonance after about 6,000 years?

Nice to find this one .  
Chiron has an identity crisis I think  Smiley
Here's the plot of its orbital period vs Saturns one . It's ornit varies heavily , peaking at 10.000y and then it stabilises into some kind of 2:1 resonance with Saturn.  
I'll post an animation of the latter part .

Here's the animation of Chiron , starting at 8.000y and running to 20.000y in rotating frame with Saturn. Jupiter is in blue .  
After 2000 years of Rock 'n roll it enters in a quasi stable orbit in a 2:1 resonance with Saturn ; probably due to a close encounter with Saturn or maybe even with Uranus .
I'm not sure how it behaves after 20.000 years , but this is the first time a see a body enter into resonance that way !

Thanks for the animation Frank.  I watered down the wording to prevent {{OR}} (Original Research) concerns.  Besides the resonance would only be temporary.

"Dwarf Planet Candidate" 38628 Huya
Reply #23 - 03/23/09 at 08:15:39
 
"Dwarf Planet Candidate" and "Plutino", 38628 Huya, is currently closer to the Sun than Neptune's orbit.  Can we plot a 20,000 year chart showing the perihelion (q) distance for Neptune, Pluto, and Huya?

I'll see what I can do  Smiley
In the meantime a picture in rotating frame to Neptune for 20.000y .  
Pluto in grey , Huya in red .

Here's the variation of distance to sol . I've reduced the timescale to some thousands years as the graph doesn't change much . It's nice to see how Pluto and Huya seem toreach closest distance to Sol more or less at the same moment .

Plutino (15875) 1996 TP66
Reply #26 - 03/23/09 at 15:32:17
 
Thank you Frank;
 
How about plutino (15875) 1996 TP66 that is currently well inside the orbit of Neptune @ 27 AU?  How does its rotating frame and/or distance plot look?

I think we should demote Pluto as a minor planet  Smiley when we see the orbit of 1996TP66 ...
In rotating frame to Neptune over 20.000y 1996TP66 shows this smooth orbit (in red ) . Pluto is shown in grey as a reference .

(120216) 2004 EW95 comes to perihelion in 2018

Thanks Frank;
 
I have added your info to the article:
http://en.wikipedia.org/wiki/(15875)_1996_TP66 (need to cut and paste)
 
I would love to see one more, (120216) 2004 EW95 that will come to perihelion in 2018 @26.95AU...
