Under some circumstances, a star can collapse into an extremely dense object made mostly of neutrons and called a neutron star. The density of a neutron star is roughly 10 times as great as that of ordinary solid matter. Suppose we represent the star as a uniform, solid, rigid sphere, both before and after the collapse. The star's initial radius was 7.0×105 km (comparable to our sun); its final radius is 17 km .

Under some circumstances, a star can collapse
into an extremely dense object made mostly of
neutrons and called a neutron star. The density of
a neutron star is roughly 104 times as great as
that of ordinary solid matter. Suppose we represent
the star as a uniform, solid, rigid sphere, both
before and after the collapse. The star's initial
radius was 7.0x105 km (comparable to our sun);
its final radius is 17 km.
