List of albedo features on Mercury

This is a list of the albedo features of the planet Mercury as seen by early telescopic observation.

Although this is not true (Mercury rotates three times on its axis for every two revolutions around the Sun), when it is positioned for best viewing from Earth, the amount by which its visible face has rotated from its previous best viewing position is fairly small.

A map of Mercury[1] made in the 1910s by astronomer Eugène Michel Antoniadi shows the following albedo features, localized by a grid in which 0° longitude is the (assumed) subsolar meridian.

The names of albedo features currently used by the Gazetteer of Planetary Nomenclature are largely based upon Antoniadi's names, but include several alterations; they also necessarily use a different coordinate grid.

Other changes are: all features named Vallis and Promontorium have been renamed Solitudo; Solitudo Argiphontae has been renamed Sinus Argiphontae ("bay of Argiphontes"); Admeti has been changed to Admetei (in error; there is no mythological figure Admeteus); Pleias has become Pleias Gallia.
