ABSTRACT
Detailed orbit integrations of clones of five Centaurs ­ namely, 1996 AR20, 2060 Chiron, 1995
SN55, 2000 FZ53 and 2002 FY36 ­ for durations of 3 Myr are presented. One of our Centaur
sample starts with perihelion initially under the control of Jupiter (1996 AR20), two start under
the control of Saturn (Chiron and 1995 SN55) and one each starts under the control of Uranus
(2000 FZ53) and Neptune (2002 FY36), respectively. A variety of interesting pathways are
illustrated with detailed examples including: capture into the Jovian Trojans, repeated bursts of
short-period comet behaviour, capture into mean-motion resonances with the giant planets and
into Kozai resonances, as well as traversals of the entire Solar system. For each of the Centaurs,
we provide statistics on the numbers (i) ejected, (ii) showing short-period comet behaviour
