Calculadora de Albedo PlanetárioFormula

## Planet Albedo

Albedo quantifies how reflective a planet is. A value of 0 means all light is absorbed; 1 means all is reflected.

### Formula

**A = F_reflected / F_incident**

The absorbed fraction is (1 - A), which determines how much stellar energy heats the planet.

Exemplo Resolvido

Earth reflects about 100 W/m2 out of 1361 W/m2 incident.

  1. A = F_reflected / F_incident
  2. A = 100 / 1361
  3. A = 0.0735
  4. This is geometric albedo at one angle; Bond albedo integrated over all angles is about 0.30
