Top us vacation spots for In one particularly famous case, that of D/ F Shoemaker-Levy, the comet, after getting trapped in an ever-decreasing short-period orbit around Jupiter, was split into pieces under tidal forces when it made a close approach to the gas giant in Then the resultant objects spread out around the orbit and collided with Jupiter the next time they passed it, in July Working out the effect of planetary perturbations on a given comet's orbit is a complex business, undertaken only by those who specialize in the ield of solar system dynamics. Nongravitational Effects The most important nongravitational effect on a comet is outgassing. Comet Encke's orbital period shortened from years at the end of the eighteenth century to years in the s.From that point it stabilized.
The reason for P/Encke's acceleration was that its spin axis was tilted in such a way that the nucleus rotated in a direction opposite to its orbital motion.

As a result, the rocket effect of its outgassing sped the comet up. Fragmentation and Destruction of Comets Comets are relatively fragile objects and sometimes break up, whether due to the explosive release of internal pressure, collisions with small solar system bodies, and/or the gravitational pull of Jupiter or the Sun.
