    Planets on planetary nebulae

    Could large planets in a planetary nebula have any detectable effects on the nebula at all?

    Since a planetary nebula is typically a light-year across, I doubt if we'd see much effect from a planet orbiting within it.
    But low mass stellar companions, including planets, can have a significant effect on the shape of the nebula as it forms.

    Thanks, grant.
    While we are talking about PNs, is it true that the sun will probably not have one? That a star must be more massive than the sun to form a Planetary Nebula?

    No, if I am not mistaken the Sun is expected to form a planetary nebula, ejecting its outer envelope as the core contracts into a white dwarf.
