subgiant compared to the size of a neutron star
Considering a neutron star is about the size of a city, a subgiant is way bigger.t's very dense. But a neutron star has collapsed from i â¦ ts precursor form, and it's only a few dozen kilometers in diameter but still has a mass of one or two times that of the sun. That makes the white dwarf larger, but less dense than the neutron star.
