| Eponym | Cleostratus |
Cleostratus is a lunar impact crater near the northwest limb of the Moon. It lies to the northeast of the crater Xenophanes, and west-southwest of the prominent Pythagoras. From the Earth this crater appears highly elongated due to foreshortening.
The rim of this crater has become soft-shouldered due to steady impact erosion, and the formation is now just a depression in the surface surrounded by an eroded rise. A pair of small craters lie across the southwest rim, forming part of a short chain of craters leading to the west. Along the crest of the southern rim is a linear ridge. The satellite crater Cleostratus E is attached to the northwest rim, and intrudes slightly into the inner wall. The interior floor of this crater is flat and nearly featureless, having only a few tiny craterlets marking the surface.
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 Cleostratus.
