    Since their paths cross, is it possible that Pluto and Neptune could collide?

    Question #42028. Asked by Hamlet.. (Dec 06 03 8:28 AM)

    Pluto's orbital period is exactly 1.5 times that of Neptune. So every time Pluto goes around the sun twice, Neptune goes around thrice. This ensures that the two will never meet.

    Also, the path of Pluto is inclined at an angle of 17.2 degrees and never truely crosses Neptune's path. In many two-dimensional orbital diagrams, it would appear that they cross, but in three dimensional diagrams, it is clear that they actually do not.
