WebMass and composition tend to divide into two principal groups: coarse particles mostly larger than 2.5 µm in aerodynamic diameter, and fine particles mostly smaller than 2.5 µm in aerodynamic diameter (PM2.5). The smaller … Web5. Whenever I see the term dust for the particles of a nebula, I ask myself whether this is actually based on some reliable measure of particle size. Of course we can all agree it looks like dust from this distance. And we all know how such appearances often lead to assumptions which are incorrect and whose incorrectness we are often blind to.
