Rupes Recta and Catena Davy craterlet trail

By |2 April 2023|Moon, News|

An interesting craterlet trail:

“This linear string of 23 tiny craters runs from the midpoint of Davy Y towards the walled basin Ptolemaeus, following a slightly curving course to the east-northeast. It is located at selenographic coordinates 11.0° S, 7.0° W, and has a length of 50 km.

This formation is not believed to be due to secondary cratering because it is not radial to a suitable source crater. The most likely cause is believed to be a single body that broke apart prior to impact due to tidal effects. High resolution images have demonstrated that the craters formed at about the same time since the ejecta from each crater does not overlay neighboring craters. However, there are still some scientists who believe that this chain of craters may be volcanic in origin.” Wikipedia
