Cajal (crater)
Crater on the Moon
From Wikipedia, the free encyclopedia
Cajal is a small lunar impact crater on the northern part of the Mare Tranquilitatis. It is a circular (9 km diameter), cup-shaped formation that lies southeast of the lava-inundated crater Jansen. Orbital imagery shows no significant degredation of the crater from subsequent impacts. To the northwest is a system of wrinkle ridges designated the Dorsa Barlow.[3]
