What are the regions of the Moon called?

What are the regions of the Moon called?

The lunar surface can be divided into two main regions, the highlands and the maria. The highlands make up roughly 83 percent of the moon’s surface, whereas the maria make up about 17 percent of its surface.

What are the dark smooth regions of the Moon?

Dark regions on the Moon are called maria, which is Latin for “seas”. So Mare Tranquilatis is the “Sea of Tranquility”. Apollo astronauts discovered that these regions are smooth, low-lying plains with relatively few craters.

What are the dark smooth plains on the Moon called?

mare, plural maria, any flat, dark plain of lower elevation on the Moon. The term, which in Latin means “sea,” was erroneously applied to such features by telescopic observers of the 17th century.

Why is the Moon’s surface dark?

When you look at the Moon, you will see dark and light areas. The dark areas are young plains called maria and are composed of basalt. The basalt flowed in and flooded the area created by a huge impact with an asteroid or comet.

What are moon craters called?

The majority of named lunar craters are satellite craters: their names consist of the name of a nearby named crater and a capital letter (for example, Copernicus A, Copernicus B, Copernicus C and so on). Lunar crater chains are usually named after a nearby crater. Their Latin names contain the word Catena (“chain”).

What are Moon Highlands?

Glossary. highlands: the lighter, heavily cratered regions of the Moon, which are generally several kilometers higher than the maria. mare: (plural: maria) Latin for “sea;” the name applied to the dark, relatively smooth features that cover 17% of the Moon’s surface.

What are Moon craters called?

Have we explored the dark side of the moon?

The Apollo 8 astronauts were the first humans to see the far side in person when they orbited the Moon in 1968. All manned and unmanned soft landings had taken place on the near side of the Moon, until 3 January 2019 when the Chang’e 4 spacecraft made the first landing on the far side.

Is there a permanent dark side of the moon?

We always see the same side of the moon from Earth The moon is tidally locked with Earth, which means that we are always looking at the same side of it. So, half of the moon is in darkness at any given time. It’s just that the darkness is always moving. There is no permanently dark side.

What’s the deepest crater on the Moon?

The South Pole–Aitken basin
The South Pole–Aitken basin (SPA Basin, /ˈeɪtkɪn/) is an immense impact crater on the far side of the Moon. At roughly 2,500 km (1,600 mi) in diameter and between 6.2 and 8.2 km (3.9–5.1 mi) deep, it is one of the largest known impact craters in the Solar System.

What are graben Rilles?

Next, we can explore straight rilles, which are thought to have formed due to tectonic forces. These valleys are graben, which form when the surface pulls apart under extensional stresses, and a block of the crust drops down to create the valley floor.

Who is the last human stepped on the moon?

Cernan
During the Apollo 17 mission, Cernan became the eleventh man to walk on the Moon. As he re-entered the Apollo Lunar Module after Harrison Schmitt on their third and final lunar excursion, he is the last man to walk on the Moon as of 2021.
