Stars of which type are the smallest in diameter?
white dwarfs
brown dwarfs
red dwarfs
neutron stars
A typical neutron star has a mass between about 1 and 2 solar masses, with a corresponding radius of just about 12 km. Some of them (pulsars), rotate as quickly as once per 33-millisecond, so their radius must be very small not to break the light speed limit at the surface level.
