Baldet (lunar crater)
Encyclopedia
Baldet is a lunar
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.
The rim of Baldet is low and worn, but generally retains its original circular shape. There is a slight outward bulge along the northwest rim, and the western interior wall is wider than elsewhere.
The flat, nearly featureless interior has been flooded by lava, and has a lower albedo
than the surroundings giving is a darker hue. A smaller crater has broken into the eastern rim, leaving a gap where the two craters intersect that has been covered in lava. A similar-sized ghost crater
lies just inside the northern rim, producing a raised ring in the crater surface. Another such formation lies just outside the southern rim of Baldet.
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...

Sphere
A sphere is a perfectly round geometrical object in three-dimensional space, such as the shape of a round ball. Like a circle in two dimensions, a perfect sphere is completely symmetrical around its center, with all points on the surface lying the same distance r from the center point...

Lava
Lava refers both to molten rock expelled by a volcano during an eruption and the resulting rock after solidification and cooling. This molten rock is formed in the interior of some planets, including Earth, and some of their satellites. When first erupted from a volcanic vent, lava is a liquid at...

Cori (lunar crater)
Cori is a lunar impact crater that is located in the southern hemisphere on the far side of the Moon. It lies less than one crater diameter to the north of the crater Baldet. To the northeast is the crater Grissom...

Minkowski (crater)
Minkowski is a lunar crater on the far side of the Moon, in the lower latitudes of the southern hemisphere. It lies about one crater diameter to the north-northeast of Lemaître, a formation of similar dimension...

Palimpsest
A palimpsest is a manuscript page from a scroll or book from which the text has been scraped off and which can be used again. The word "palimpsest" comes through Latin palimpsēstus from Ancient Greek παλίμψηστος originally compounded from πάλιν and ψάω literally meaning “scraped...
