Healy (crater)
Encyclopedia
Healy is a lunar
crater
that lies past the northwestern limb of the Moon
, on the far side relative to the Earth
. It is located to the southeast of the walled plain Landau
, and west of Lorentz
, another walled plain. The rim of Healy is only slightly worn, but a small crater lies across the northeastern side. The inner walls and interior floor are relatively featureless, with no impacts of note.
Moon
The Moon is Earth's only known natural satellite,There are a number of near-Earth asteroids including 3753 Cruithne that are co-orbital with Earth: their orbits bring them close to Earth for periods of time but then alter in the long term . These are quasi-satellites and not true moons. For more...

Impact crater
In the broadest sense, the term impact crater can be applied to any depression, natural or manmade, resulting from the high velocity impact of a projectile with a larger body...

Landau (crater)
Landau is a large lunar crater that is located in the northern hemisphere on the far side of the Moon. It was named after physicist Lev Landau. The crater Wegener is attached to the northeastern rim. Attached to the southeastern rim is Frost....

Lorentz (crater)
Lorentz is a huge lunar crater that lies just beyond the northwest limb of the Moon, in a region that is brought into sight of the Earth during favorable librations. This formation is nearly as large as the Mare Nectaris on the near side of the Moon, although it has not been submerged by lava as...
