Cayley is a small impact crater in an area flooded by basaltic lava west of the Mare Tranquillitatis . The round, bowl-shaped structure lies northwest of the two craters De Morgan and D'Arrest and has an inner plane that takes up about a quarter of the diameter of the crater. The inner slopes are relatively light in color and stand out clearly from the surroundings. However, Cayley is not nearly as bright as the somewhat larger Dionysius crater in the east-southeast, from which it also stands out due to the lack of a radiation system.
To the west and slightly to the north is Whewell Crater , which is roughly the same size. In the north extends the Rima Ariadaeus , which has an east-southeast orientation.
The terrain surrounding the crater is somewhat similar to the lunar mare , but has a higher albedo and is overlapped on the eastern edge by the mare Tranquillitatis . Lunar scientists suspect that this plain was formed as a result of the deposition of ejecta from an impact basin. The most likely source is the Mare Imbrium in the northwest.
