Results from a series of long-term numerical integrations of orbits centred on that of C/1995 O1 (Hale-Bopp) are presented. Initially, 33 orbits taken from various sources were integrated in realistic models of the solar system for various time-scales about the present in the range (-3, +2) Myr and analyzed to assess the probability of different dynamical outcomes, such as a sungrazing state or the number of orbits since it was captured from a long-period orbit in the Oort cloud. ...
