    is planet #9 needed or can a close pass by a star do it ?

    it was said the outer planets did not follow a expected orbit because an other unknown mass was effecting them
    that was the listed explanation for the search for Neptune and pluto at the time they were found

    was that a flawed mr N based math idea or does mr E's relative revisions also produce an extra mass out there needed to explain the orbits

    and would the close passing of a star be a good solution to the orbits problem without extra planets needed ?
    or is the only solution an other planet out there ?

    We've got a Planet Nine thread, it covers the general possibilities pretty well.

    The current consensus is that it's a transient concentration of mass from the comets moving around in the outer Solar System. No planets or close-passing stars have ever been found there.

    yes I have read the #9 thread

    I still do not understand if the orbit problem is a one time effect like a close star passing by
    or needs an existing mass that has a constant input like a bound planet would have

    AFAIK the close passing star hypothesis has been ruled out. No passing stars fit the time frame of when the orbits would have been affected.
