Geddes is a crater on Mercury. It has a diameter of 84 kilometers. Its name was adopted by the International Astronomical Union (IAU) in 2010. Geddes is named for the Irish stained glass artist Wilhelmina Geddes, who lived from 1887 to 1955.[1]
Within Geddes is a relatively large irregular depression, making it a pit-floor crater. Such pits are thought to be caused by volcanic activity.[2]
