## 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.

计算示例
Earth reflects about 100 W/m2 out of 1361 W/m2 incident.
- A = F_reflected / F_incident
- A = 100 / 1361
- A = 0.0735
- This is geometric albedo at one angle; Bond albedo integrated over all angles is about 0.30
