Krylov is a lunar impact crater on the far side of the Moon. It lies about one crater diameter to the northwest of Cockroft, and due west of Evershed.
Lunar craters are impact craters on Earth's Moon. The Moon's surface has many craters, almost all of which were formed by impacts.
An impact crater is an approximately circular depression in the surface of a planet, moon, or other solid body in the Solar System or elsewhere, formed by the hypervelocity impact of a smaller body. In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. Impact craters range from small, simple, bowl-shaped depressions to large, complex, multi-ringed impact basins. Meteor Crater is a well-known example of a small impact crater on Earth.
Earth's Moon is an astronomical body that orbits the planet and acts as its only permanent natural satellite. It is the fifth-largest satellite in the Solar System, and the largest among planetary satellites relative to the size of the planet that it orbits. The Moon is, after Jupiter's satellite Io, the second-densest satellite in the Solar System among those whose densities are known.
This crater has been worn by impact erosion, leaving the features rounded and somewhat irregular. But the perimeter of the rim can still be traced in the rugged surrounding terrain. There is a small, fresh crater laid across the eastern rim, and some old and worn depression along the southern and western inner wall. On the whole, there is little to distinguish this crater from the multitude of other impacts in this region.
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Krylov.

Anaximenes is a low-rimmed lunar impact crater near the north-northwest limb of the Moon. It lies to the west of the crater Philolaus, and northeast of Carpenter. To the northwest is Poncelet, close to the visible edge of the Moon.
Arrhenius is a lunar impact crater that is located just on the far side of the Moon, near the southwest limb. In this location the vicinity of the crater can be viewed during favorable librations, although it is viewed from on edge. To the south-southeast is the worn crater Blanchard, and De Roy lies further to the west.
Artem'ev is a lunar impact crater that is located on the far side of the Moon. The rim of this crater has been modified by subsequent impacts in the vicinity, with an inward bulge along the southwest edge and a worn impact lying across the north rim. The satellite crater Artem'ev G is partly overlain by the southeast rim of Artem'ev. The crater interior is relatively flat, and marked only by tiny craterlets.
Asclepi is a heavily eroded lunar impact crater that lies in the rugged southern highlands of the Moon. The outer rim has been worn down and rounded by many millions of years of subsequent impacts, so that it is now nearly level with the surrounding terrain. As a result, the crater is now little more than a depression in the surface. The interior is nearly flat and relatively featureless.
Avicenna is a lunar impact crater that lies on the far side of the Moon, just beyond the western limb on the northern rim of the Lorentz basin. It is named after the Persian physician Avicenna. It lies to the north-northwest of the larger crater Nernst, and to the southeast of Bragg.
Avogadro is an ancient lunar impact crater that is located in the northern hemisphere on the far side of the Moon. The formation has been heavily worn and eroded by subsequent impacts, so that the rim is now little more than a rounded edge surrounding the crater depression. The crater floor is equally worn, being covered in a multitude of smaller craters of various sizes. Many of these smaller craters have also been eroded, leaving little more than a faint trace on the surface.
Byrd is an irregular lunar impact crater that is located near the north pole of the Moon. The north rim of Byrd is nearly connected to the crater Peary, a formation that is adjacent to the pole. The smaller crater Gioja is attached to the remains of the southwest rim.
Baco is a lunar impact crater that lies in the rugged southern highlands on the near side of the Moon. The rim and inner wall has been eroded and worn by countless minor impacts since the original formation of the crater. As a result, any terraces have been worn smooth and the rim is overlaid by several tiny craterlets. The interior floor is nearly flat, with no characteristic central peak at the midpoint and no small craters of significance.
Belyaev is a lunar impact crater that is attached to the outer edge of the Mare Moscoviense, on the far side of the Moon. It is a worn formation with a small crater pair overlaying the southern rim, and several smaller craters across the relatively irregular interior.
Baldet is a lunar impact crater that is located on the southern hemisphere on the far side of the Moon. It lies in the lava-flooded region between the craters Cori to the north, Stoney to the southwest, and the worn walled plain Minkowski to the southeast.
Buisson is a lunar impact crater that is located on the far side of the Moon. It is named after the French physicist Henri Buisson. Nearly attached to the southeast rim is the crater Vesalius. To the southwest is Einthoven. The rim of this crater is somewhat worn, and is lowest in the north. There is a low central ridge across the midpoint.
Casatus is a lunar impact crater that is located near the southern limb of the Moon. The north-northeast rim of the crater overlies a portion of the slightly larger crater Klaproth. Along the western rim, Casatus A intrudes somewhat into the interior, producing an inward-bowing rim. To the southeast of Casatus is Newton.
Cannizzaro is a lunar impact crater that is located on the Moon's far side as seen from the Earth, just beyond the northwestern limb. It lies in a region of the surface that is sometimes brought into view due to the effects of libration, but not much detail can be seen since this feature is viewed from the side. The crater lies across the southwestern rim of the much larger-walled plain Poczobutt.
Dove is a small lunar impact crater that is located in the rugged lunar highlands in the southeastern part of the Moon. It lies to the north of the prominent crater Pitiscus.
Chernyshev is a lunar impact crater that is located in the northern part of the Moon's far side. It lies to the northeast of the crater Chandler, and to the southeast of the walled plain D'Alembert.
Chandler is a lunar impact crater in the northern hemisphere, on the Moon's far side. It lies to the southeast of the large walled plain D'Alembert, and southeast of the slightly smaller Chernyshev crater.
Douglass is a lunar impact crater on the far side of the Moon. It lies to the southwest of the crater Frost and south-southwest of the large walled plain Landau.
Dziewulski is a lunar impact crater on the far side of the Moon. It lies between the craters Edison to the north and Popov to the south. The outer rim of this crater has been considerably worn by impacts, particularly along the southwest quadrant where the satellite crater Dziewulski Q overlies the rim and the interior floor. The northern rim is also heavily disrupted, and several small crater lie along the southeast rim. The interior floor and surrounding terrain has been resurfaced.
Ehrlich is a small lunar impact crater named after the German scientist Paul Ehrlich. It is located in the northern hemisphere on the Moon's far side. It lies within a rugged region that has been extensively bombarded by impacts of comparable size. Ehrlich lies about midway between the craters Parsons to the south and the heavily worn Guillaume to the north.
Fowler is a large lunar impact crater that lies in the northern hemisphere on the Moon's far side. It lies to the south-southwest of the crater Esnault-Pelterie, and north of Gadomski. Overlying the eastern rim and intruding into the interior is Von Zeipel.
Ewen Adair Whitaker was a British-born astronomer who specialized in lunar studies. During World War II he was engaged in quality control for the lead sheathing of hollow cables strung under the English Channel as part of the "Pipe Line Under The Ocean" Project (PLUTO) to supply gasoline to Allied military vehicles in France. After the war, he obtained a position at the Royal Greenwich Observatory working on the UV spectra of stars, but became interested in lunar studies. As a sideline, Whitaker drew and published the first accurate chart of the South Polar area of the Moon in 1954, and served as director of the Lunar Section of the British Astronomical Association.
