# Geometric albedo facts for kids

The **geometric albedo** of an astronomical body is the ratio of its actual brightness at zero phase angle (i.e. as seen from the light source) to that of an *idealized* flat, fully reflecting, diffusively scattering (Lambertian) disk with the same cross-section.

The **visual geometric albedo** refers to the geometric albedo quantity when accounting for only electromagnetic radiation in the visible spectrum.
