Its quite possible 2004EW95 will come at perihelion in 2018 .  
In rotating frame to Neptune over 30000 years it looks like this ...

Plutinos
Reply #31 - 03/26/09 at 13:39:18
 
In order to attempt to visualise the orbits of the three Plutinos above ( Huya, 1996T66 and 2004EW95 ) referenced to Pluto I made this rather unusual  animation herunder .  
The animation shows the orbits of the three bodies in rotating frame with Pluto .  
Pluto is he grey line at 6 'o clock . Neptunes orbit appears as the half circle in grey .
Due to the high eccentricity of Plutos orbit the orbit of Neptune sometimes seems to recede in this representation .  
Animation was run for 19500 y , and has 79 frames each covering 247.2 years being Plutos orbital period.

I've made a selection of the known Plutinos , orbiting just as Pluto in a 2:3 resonance with Neptune :
Hereunder are represented  
2002VX130, Orcus, Ixion , 2007JH43, Huya, 1999TC36, 1996TP66, 2005TV189 and 2004EW953
in a rotating frame with Pluto .  
Animation was run for 195700 years . Each frame covers 1.5 * 164.8 years .  
Neptune itself is not represented ( made invisible ) .  Pluto is the white line at 6 'o clock .  
While most Plutinos are synchronised with Plutos libration this is not the case for all of them .
