2. Is it located within the Milky Way Galaxy? Yes.
3. Is it smaller than a planet? No.
4. Is it less dense than a typical star? I would assume so.
5. Is it self illuminating? In a manner of speaking, yes.
6. Are its EM emissions mainly outside the visible band? Yes, I believe so.
7. Is it nebular? Not exactly.
8. Is it smaller than the Sun in diameter? No.
9. Is it part of a star? I suppose one could make that case.
