Cajal (crater)

Cajal is a tiny lunar impact crater on the northern part of the Mare Tranquilitatis, in memory of the Spanish doctor and Nobel laureate Santiago Ramón y Cajal. It is a circular, cup-shaped formation that lies to the southeast of the lava-inundated crater Jansen. Cajal was formerly designated Jansen F, prior to renaming by the IAU. Also to the northwest is a system of wrinkle ridges designated the Dorsa Barlow.
