In the much slighter gravity of any other type of planet or star (except from a black hole) the pressure will not be enough to maintain the density of the Neutronium. Any tiny world that had enough neutronium to give it sufficient escape velocity to retain a dense atmosphere would have a high enough mass and density that we would already know about it, if it was anywhere in our solar system except for the farthest and least known dwarf planets. | |
