An article of 2013 describes the long term evolution of this Trojan .
It seems to be a "temporarely" trojan to Uranus .
http://arxiv.org/abs/1303.5774 I made a long term integration of this object in past and future .
It seems to move from a tadpole orbit to a horseshoe orbit regularly in the future , so it was in the past .
According to my sim it will escape the horseshoe orbit in about 600 kY from now , and never return again in the coming 3 My . Its orbit goes chaotically and will pass Neptunes orbit .
In the past : it seems to have been a trojan for about 1.2 My to Uranus .
Before that it also had a rather chaotic orbit , sometimes crossing Saturns orbit , as well as Neptunes orbit .
My sim suggests that it became a trojan to Uranus due to a close encounter with Uranus at 0.14 AU around 1.3 MY in the past .
