QUESTION: If you were to scoop up a 10 cm cube of material from an average neutron star, how much mass would the cube have?
ANSWER: at a rough average density of 10^17 kg/m^3, if you scooped up a 0.10 m cube of material from a neutron star, it would weigh roughly 10^14 kg
This is roughly the mass of Halley's Comet, which has a mean diameter of 11 km. All that mass packed into a 10cm x 10cm x 10cm cube. Neutron stars are dense!
