Black Hole Classifications
| Class | Mass | Size |
|---|---|---|
| Supermassive black hole | ~105-1010 MSun | ~0.001-400 AU |
| Intermediate-mass black hole | ~103 MSun | ~103 km ≈ REarth |
| Stellar black hole | ~10 MSun | ~30 km |
| Micro black hole | up to ~MMoon | up to ~0.1 mm |
Surface Gravity of a Black Hole - Gravitational Force Calculation
Formula:
gB = [G•M / rs²]
where,G = gravitational constant (6.67*10-11 Newton-meter2 / kg2),
m = the mass of the black hole (kg),
rs = schwarzschild (gravitational) radius (m),
gB = black hole surface gravity
