Calcolatore Densita Stella di Neutroni — Formula
## Neutron Star Density
### Formula
**rho = 3M / (4π r³)**
A typical neutron star (1.4 M_sun, 10 km radius) has an average density near nuclear density (~2.3 × 10¹⁷ kg/m³). A sugar-cube-sized chunk would weigh about a billion tonnes.

Esempio Risolto
A 1.4 M_sun neutron star with r = 10 km.
- rho = 3M / (4π r³)
- 4π r³ = 4π × (10000)³ = 1.257e13 m³
- rho = 3 × 2.78e30 / 1.257e13 = 6.63e17 kg/m³
- About 2.9 times nuclear density.
