Holden (lunar crater)
Holden is a lunar crater attached to the southeast rim of the much larger crater Vendelinus. The crater rim is impacted by a craterlet on the north-northwest, and it possesses a terrace along the northeast interior wall. The floor of the crater is flat with no central peak. There is a small crater on the floor just to the south of the midpoint. It is named after Edward Singleton Holden. A crater with the same name exists on Mars.
==Satellite craters==
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Holden.
