Neutron stars are bounded by mass, somewhere in the neighborhood of 3 solar units it seems (if it were more massive it would collapse further), so I think their radius is bounded too (since if it was too large then it wouldn't be dense enough to be a neutron star). It seems like the likely radii for neutron stars are around 10km.

- mtdewcmu 13y agoThis area of astronomy still contains a lot of conjecture, as far as I can tell, and it could change. A recent Scientific American article made a case that black holes might not exist, but, instead, quantum mechanical effects would intervene and prevent a star from collapsing past the radius of the event horizon. They called the resulting not-quite-a-black-hole a black star (N.B., not the hip hop act featuring Mos Def and Talib Kweli). Black holes themselves are considered to have a spin, so since their radii are infinitesimal, they are the rotation champs.
