Definition

A geographic area on the surface of a planet or satellite that is distinguished from adjacent terrains by a difference in brightness or albedo.

Classical albedo features have been identified with Earth-based telescopes, while no detailed morphology could be resolved. Time-varying albedo features can be due to seasonal changes, for example, due to frost covers or due to the redistribution of bright dust or dark sand sheets by aeolian activity. Thanks to high-resolution imagery on board of space probes, albedo feature nomenclatures are increasingly replaced with detailed feature descriptions.
