  • Not enough to keep ANY atmosphere. This is the part you are hung up on apparently.

    Yes nebulae are visible because they are particles spread usually METERS apart, that’s only visible as a cloud THOUSANDS of light years away. If you were in the center of the nebulae it would be invisible from that perspective. Like being on earth and looking at the moon, there wouldn’t be enough density of particles to say, hey there’s “smog” there. Because the particles float away freely, unlike on earth. And they are also helped carried away by solar winds too. Which you know the atmosphere helps prevent on earth on other planetary bodies….
