             English: Histogram of the  aphelia of the 186  comets listed by the  MPC in June 2005. The  abscissa is the  natural logarithm of the aphelia, expressed in  AUs. The grouping at  Jupiter's  orbit dominates, but the  Saturn,  Uranus, and  Neptune groups can also be seen. Diagram prepared by  User:Urhixidur and donated to the public domain.
