Early planetary formation thought

    Greetings !

    Some less popular theories, at this time,
    suggest that planets formed or at least
    began to form before the Sun had formed.
    I'm not sure that I agree with that, but
    it's worth remembering as another counter
    example to the idea I just thought about.

    Anyway, the idea I just thought about is:
    Suppose that the planets formed after the
    Sun(Sol) was formed. Now, is it possible
    that the gravitational pull of the Sun on
    the one hand and the pressure of the solar
    wind and aspecialy solar radiation on the
    other hand could've created certain La'grange
    points for various types of ellements and
    molecules in the early solar nebula that
    could've somehow affected planetary formation ?
    Or, were such points too far away for the powerful
    emmissions of the early Sun which is also
    why all the free matter got blown away into
    our Oort cloud ?

    All opinions are welcome. :smile:

    Live long and prosper.
