I was told that neutron stars are what happens when a star is so dense that the protons and electrons fuse to form neutrons. By this logic, neutron stars are just very big sky isotopes.
Notes:
I didn't draw the electrons because those things are too confusing.
The number 10^56 is an approximation, from the sun's mass (10^30) times grams in a kilogram (10^3) times Avogadro's number (10^23). Arguably it should round up to 10^57 but whatever.
All of this is probably very untrue, please don't use it for anything important
