Neutron stars are smaller than white dwarfs.

Here's why:

* White dwarfs are the remnants of stars like our Sun. They are about the size of the Earth, containing a mass similar to the Sun squeezed into a much smaller volume.

* Neutron stars are formed from the collapse of much more massive stars. They are incredibly dense, with a mass several times greater than the Sun packed into a sphere only a few miles across.

So, while white dwarfs are smaller than the stars they came from, neutron stars are even smaller and denser, making the initial statement incorrect.
