10 Prominent Lunar Craters

Lunar craters are cup-like depressions on the Moon. These are the remains of collisions between an asteroid, comet and the Moon. The surface of the moon is scarred with millions of impact craters. The following are some prominent lunar craters.

Deepest craters:

The following are some of the deepest lunar craters.

Moretus

Moretus is the deepest lunar crater with a depth of 5.0 km. it is located near the south pole of the moon. The crater appears oblong and the floor is flat.

Tycho

Tycho has a depth of 4.8 km. It is surrounded by a distinctive ray system that forms long spokes which can reach as long as 1,500 km. These rays can be observed when this crater is illuminated by earthlight.

Piccolomoni

Piccolomini has a depth of 4.5 km. Piccolomini is formed 3.2 to 3.8 billion years ago. The floor of the crater is smooth with only minor hills.

Longomontanus

Longomontanus is an ancient lunar impact crater with a diameter of 145 km and depth of 4.5 km.  It is called a walled plain due to the variety of large lunar formations.

Albategnius

Having a depth of 4.4 km and a diameter of 129 km Albategnius is an ancient lunar impact crater. The outer wall is hexagonal and eroded with impacts, valleys and land ships.

Largest craters:

The following are some of the largest lunar craters.

Bailly

Bailly is the largest crater on the near side of the Moon with a diameter of 303 km and depth of 4.3 km. This can be visible during full moon days. Bailly has remained free of lava flooding and is covered with a multitude of ridges and craters. This crater is estimated to be more than 3 billion years old.

Schickard

Having a diameter of 227 km Schickard is the second largest crater. It appears oblong due to foreshortening as it lies near the lunar limb. The floor of this crater is partially flooded by lava and the other portion is rough-textured.

Clavius

Clavius is the third largest crater with a diameter of 225 km and depth of 3.5 km. This crater is estimated to be about 4 billion years old. Clavius can be seen as a notch about one or two days after the moon reaches first quarter.

Humboldt

Humboldt is a large lunar crater with a diameter of 207 km. The depth of this crater is unknown. This crater is an irregular circle having a network of clefts forming a pattern of radial spokes and concentric arc on its surface floor.

Maginus

Maginus is a large lunar with a diameter of 194 km and a depth of 4.3 Km. It is located in the southern highlands. The floor of this crater is flat and it has a pair of low central peaks.

    Excellent pictures. 1 kilometer = 3,281 feet. The deepest crater you’ve displayed, Moretus, is 5.0 km. That’s deeper than the oceans on Earth:

    Average depth of Atlantic ocean: 3926 m (4 km)
    Average depth of Pacific ocean: 4282 m (4.2 km)
    Average depth of Indian ocean: 3963 m (4 km)

    So, if we filled some of the deepest craters on the Moon and Mars with water, we’d have instant oceans. That’s probably how Earth’s oceans formed, they were craters which just filled up with rainwater over the millenia. Smaller craters would make instant ponds, lakes, and even rivers.

    Remember, all mammals (groundhogs, squirrels, gerbils, weasels, lorises,lemurs, cows, pigs, chickens, sheep, etc) which respire aerobically, give off water vapor and CO2 as byproducts of Aerobic Respiration, 24/7. Water vapor condenses to water droplets upon cooling. These are the same byproducts from hydrocarbon combustion. So, the more we cook, and the more we eat, and the more active we are, the more water vapor, CO2 and methane gas we add to a planet’s atmosphere, 24/7. All 3 are potent greenhouse gases which will build a rich and thick atmosphere over time. Pretty soon it’ll be raining and flooding on the Moon and on Mars.

    continued…
    Earth’s oceans of water absorb much of the dangerous radiation which bombards us, and tons of micrometeorites could be collected by lunar basins, adding to the overall MASS of a planet over time. Added MASS means added GRAVITY. That’s probably how Earth’s oceans formed, they were craters which just filled up with rainwater over the millenia. Smaller craters would make instant ponds, lakes, and even rivers.
