This dynamically-interesting object approached Jupiter to 0.334 +/- 0.001 AU
on 1938 Apr. 14.3 and 0.129 +/- 0.001 AU on 1855 July 31.8 +/- 0.1. Future
approaches within 1.0 AU of Jupiter occur on 2039 Jan. 22.1 (0.765 AU), 2049
Nov. 11.8 +/- 0.7 (0.911 +/- 0.002 AU), 2056 May 27.8 (0.310 +/- 0.001 AU),
2061 Dec. 12.0 +/- 0.5 (0.521 +/- 0.005 AU) and 2144 Sept. 4.6 +/- 1.0
(0.282 +/- 0.001 AU).

A plot of the motion of 2006 UG185 over the time period 1900-2100, in a
Jupiter-fixed reference frame, is available at:

Also available, for comparison, are plots of the motion of a (588) Achilles
(a routine Jupiter Trojan) and 39P/Oterma (a comet that underwent two close
encounters with Jupiter in the last century):
