Cremona (crater)
Encyclopedia
Cremona is a lunar
crater
that is located long the north-northwestern limb of the Moon
. From the Earth
this crater is viewed from the side, and the visibility is affected by libration
effects. To be viewed in any detail, this crater must be seen or photograph
ed from orbit. It is located midway between the crater Boole
to the south-southeast and, on the far side of the Moon, the crater Lindblad
.
This is a relatively old, worn crater that is overlaid by a number of smaller craters. The rim has been worn down and rounded by lesser impacts, leaving only a wide depression in the surface with somewhat irregular interior walls. Small craters lie across the north and northwestern rims, and the satellite crater Cremona L is laid across the southern rim. A band of tiny craterlets lies across the northeastern part of the rim, continuing part of a pattern of multiple craterlets that continue to the north.
The craters Cremona B and C form a double-crater pair in the northwestern part of the floor. The inner wall on the western side is unusually wide, forming a rough interior surface. The floor in the eastern half is more level, and contains the remnant of a central peak attached to the eastern rim of Cremona C.

A photograph is an image created by light falling on a light-sensitive surface, usually photographic film or an electronic imager such as a CCD or a CMOS chip. Most photographs are created using a camera, which uses a lens to focus the scene's visible wavelengths of light into a reproduction of...

Boole (crater)
Boole is a lunar crater that lies along the northwestern limb of the Moon, to the northwest of the crater Gerard. At this location it is viewed nearly from the side, and is very oblong in shape due to foreshortening. The crater formation is nearly circular, however, with a wide inner wall that has...

Lindblad is an old lunar crater that is located on the far side of the Moon, just beyond the northwestern limb. This formation is located to the southeast of the crater Brianchon, and northeast of Cremona....
