W. Bond (crater)
Encyclopedia
W. Bond is an irregularly shaped lunar
walled plain that is located in the northern part of the Moon
, to the north of the Mare Frigoris
. It lies to the east of the crater Birmingham
, and south-southwest of Barrow
. Epigenes
is located just to the northwest of the outer rim. Along the southwest edge, between W. Bond and the lunar mare
, is the crater Timaeus
.
What remains of the outer rim of W. Bond has been eroded and reshaped until it now consists of little more than an outline of hills and mounts. The most prominent of these is a nearly linear range along the northwest rim, which is divided in half by the satellite crater W. Bond A. The southeast rim is also relatively well defined, but the remainder is irregular, notched, and not very prominent.
The interior floor is relatively flat in comparison with the rim region, although there are sections of rough terrain near the northern rim. In the center of the walled plain is a narrow rille
that runs toward the eastern rim. To the southeast of this formation is W. Bond B, a circular, bowl-shaped crater. The smaller W. Bond C is located just to the northeast.
In older publications this formation was identified as W. C. Bond.
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...

Barrow (crater)
Barrow is an old lunar crater that is located near the northern limb of the Moon. It lies between the crater Goldschmidt to the northwest and the irregular formation Meton to the northeast. To the southwest is W. Bond....
. Epigenes
Epigenes (crater)
Epigenes is a lunar crater that is located in the north part of the Moon, and is sufficiently close to the northern limb to appear significantly foreshortened from the Earth. It lies just to the northwest of the remains of the walled plain W. Bond. Due north of Epigenes is Goldschmidt, and the...

Lunar mare
The lunar maria are large, dark, basaltic plains on Earth's Moon, formed by ancient volcanic eruptions. They were dubbed maria, Latin for "seas", by early astronomers who mistook them for actual seas. They are less reflective than the "highlands" as a result of their iron-rich compositions, and...

Timaeus (crater)
Timaeus is a lunar crater in the northern part of the Moon, on the north edge of Mare Frigoris. It forms part of the southwestern wall of the large and irregular walled plain W. Bond. The rim of Timaeus is somewhat pentagonal in shape, with rounded corners...
