Capella (crater) : ウィキペディア英語版 | Capella (crater)
Capella is a lunar crater in diameter that lies to the north of the Mare Nectaris, in a rugged region with many small impact craters. It intrudes slightly into the eastern rim of the crater Isidorus, a feature only slightly smaller in diameter. The wall of Capella is low but relatively thick and irregular, with a large promontory intruding on the south-eastern side. The crater is crossed by a deep rift, the Vallis Capella, which passes directly through Capella from the north rim through the southeast side of the wall, and extends out both sides for a combined distance of 110 kilometers. This feature was formed by a chain of craters. In the middle of the crater is a wide, round peak with a craterlet at the top. The western side of the crater is dotted with impact debris, forming clusters of small hills. The crater was named for Marcianus Capella, a writer of Late Antiquity. ==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 Capella.
