@CuriousOne If you make that an answer, I think it'll be the best so far.

While in terms of content I can see why this is a sort of duplicate, the question isn't particular to planets (or anything else).

comment How do star densities work?
That's right. That falls into the part about how really you have to solve the full equations to know. The homology relations always rely on a particular set of assumptions (and approximations about things like opacity and nuclear reaction rates) that are valid only for some class of star. On the main sequence, they're usually for "zero age": i.e. when nuclear reactions begin and the star is still chemically homogeneous.

I thought this summary gave some good ideas.

comment How bright would the sun appear from the hypothetical Planet Nine proposed by Caltech?
+1 because I think it's more useful to compare the brightness to distant stars as seen from Earth. I see that this would make the Sun still much brighter than Venus appears on Earth ($M\approx-4.6$, according to Wikipedia).
