EponymZeno of Citium

Zeno is a lunar impact crater located near the northwestern limb of the Moon. It lies to the east-southeast of the crater Mercurius. Farther to the east of Zeno, along the limb, is the well-formed crater Boss.

The rim of Zeno is slightly distorted and has received some erosion due to subsequent impacts. There is a depression in the surface attached to the eastern rim, forming a bulging extension. Small craters lie on the southern rim and across the interior of the northern wall. The crater Zeno B is attached to the exterior of the southwestern rim, and the distorted Zeno A is attached in turn to the western rim of Zeno B.

Satellite craters[edit]

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Zeno.
