Moon meteorites generally fall on a lot of places

Lunar meteoriteA meteorite that after the Moon is hit by an asteroid, lunar material enters Earth-Moon space and then falls to Earth.

Lunar meteorites are a type of chondrite-free meteorite, and lunar meteorites are roughly divided into three types according to their different positions in the parent lunar body: lunar highland plagioclase, lunar sea basalt, and lunar sea still sea stone and mixed rock. They are from the junction of the Moon Highlands, the Moon Sea, and the Highlands and the Moon Sea.

It was determined by comparing it with samples retrieved from the moon by humans. If a meteorite is found to have all the characteristics of a meteorite, there is no black-gray molten shell, and there is a layer of transparent vitreous molten shell of about one millimeter after knocking, it can be judged as the weather vane of the meteorite falling on the moon. The discovery and research of lunar meteorites has promoted the identification and research of Martian meteorites.

The first lunar meteorite, the Yamato 791197, was discovered in Antarctica in 1979, but it was not known where it came from at the time. The first meteorite confirmed to originate from the Moon was Allan Hills 81005, discovered in Antarctica in 1981. At that time, more than 20 other meteorites were also confirmed to have originated from the Moon, weighing a total of about 8 kilograms.

Evidence that the meteorite originated from the Moon comes from a comparison of the mineralogy, chemical composition, and isotopic composition of lunar rocks collected by the Apollo program. The first lunar meteorite to be pinpointed** was Sayh al Uhaymir (SAU) 169, discovered in Oman in 2002. The meteorite is believed to have formed from the impact of the Lalande crater 340,000 years ago.

There are more lunar meteorites on the moon, and there don't seem to be many other places.

Summary. Hello!Glad to answer for you!

First of all, lunar meteorites, divided into igneous rocks and sedimentary rocks, are meteoroids hitting the moon, rocks pop up from the moon, captured by the earth's gravitational field, and fall to the earth's lunar rocks, they have a fusion crust with high blisters, but the iron content is much less than 1%, so the lunar meteorite is almost not magnetic, the shell is wrapped in a thick glaze, porous with blisters, hard and loose, almost non-magnetic is the characteristic of lunar meteorites, because the lunar meteorite is a fragment that pops up on the moon, it is not very large, its shape is irregular, it is difficult to see the positive sphere. Hope mine is helpful to you!Have a great day!

You probably want to ask why there are not as many craters on Earth as there are on the Moon.

In fact, the space environment of the Earth and the Moon is almost the same, and the gravitational pull of the Earth is dozens of times stronger than that of the Moon, so the Earth must have been bombarded by meteorites much more than the Moon in the early days (attracting small celestial bodies to fall is a major means for celestial bodies to accumulate their own mass). However, due to the presence of the atmosphere and liquid water, the smoothing effect on the Earth's surface is much stronger than that of the Moon. Small craters with a diameter of less than 1 km can exist on the surface for only tens to millions of years, and the maximum life of large craters with a diameter of tens of kilometers does not exceed 1 billion years, and even the large scars formed by the bombardment of large celestial bodies with a diameter of hundreds of kilometers in the early days of the earth do not exist for more than 2 billion years.

They are either filled with sediments, abrasive, or destroyed by geological movements, and eventually become unrecognizable.

The surface of the moon is a vacuum, dead environment, and lunar features are only eroded by the solar wind or cosmic rays, and this effect is very weak. Of course, the lunar surface is bombarded by new meteorites, and new craters and projectiles will destroy the old ones, but there will always be many craters left for us to see. This is why there are far more craters on the surface of the moon than on the ground.

Because the Earth has an atmosphere, most meteorites are burned up when they enter the Earth's atmosphere, and only a few larger meteorites reach the Earth's surface.

The Moon has no atmosphere, and all meteorites that rush to the Moon will not burn up, but will directly reach the surface of the Moon.

This is the reason why there are more meteorites on the Moon and fewer on Earth.

Because the earth has an atmosphere, meteorites will rub and burn when they pass through the earth's atmosphere, and the small meteorites will burn up by the time they hit the ground. Larger meteorites will be grilled very small after passing through the atmosphere, and the power of hitting the ground is very small, and there is no atmosphere on the moon.

Meteorites are prone to occur on the Antarctic continent.

In total, more than 30,000 meteorites have been discovered on the Antarctic continent so far, compared to 3,000 in other parts of the planet.

Since the Antarctic continent is covered by an ice sheet up to several kilometers thick, when a meteorite lands on the Antarctic ice sheet, it will shoot directly into the ice at a depth of several hundred meters, so that it is rarely eroded by external weathering and is preserved inside.

Then as the Antarctic glacier moves, it is brought to a lower elevation so that the meteorites scattered on the ice sheet are concentrated at the end of this glacier, and as the ice melts, the meteorites are left in place, so there are often a large number of other meteorites around the area where the meteorite is found in Antarctica. At the same time, on the ice-covered continent of Antarctica, as long as stones are found, they are basically meteorites.

The inside is of high purity and free of impurities, the whole body is covered with dense small bubbles, there is a thaw shell on the outside, there are flow lines on the melt shell, and sometimes there will be large air marks on the outside and under the thaw shell.

A meteorite is a stony, iron-like or mixed material of unburned cosmic meteors outside the Earth that break away from their original orbits or scatter into fragments on the surface of the Earth or other planets, also known as "meteorites".

Most meteorites come from the asteroid belt, and a small number come from the Moon and Mars. Meteorites are usually divided into three categories according to the level of iron-nickel metal content in their interior: stony meteorites, iron meteorites, and stony-iron meteorites.

The iron-nickel metal content in stony meteorites is less than or equal to 30%; The iron-nickel content of stony-iron meteorites is between 30% and 65%; Iron meteorites contain 95% or more iron-nickel metal.

Collisions between small celestial bodies often change the structure and structure of their interiors. For example, chondrites can be changed to nochondrites, and of course, nodulares can be transformed into chondrites.

A small celestial body falling to the ground is a meteorite. When it passes through the earth's atmosphere, it produces strong friction with the air, and under the action of high pressure and high temperature, its appearance will often melt and deteriorate, and after cooling, a layer of molten crust with a thickness of about one millimeter will be born on the surface of the meteorite.

Generally speaking, there are two kinds of molten crusts of the same meteorite, one is the molten crust produced by the collision between asteroids in space, and the other is the molten crust produced by entering the Earth's atmosphere and rubbing against the air.

Lunar meteorites are divided into two categories: igneous rocks and sedimentary rocks, and lunar basalt is one of the main rocks that make up the moon, with black colors, white, dark purple, purple red, red, mixed colors, etc. Speckled structures and almond structures are common, and biotite and phlogopite are present. There are also pyrite, chalcopyrite, chalcopyrite, and unknown minerals.

Plate-like or flat-columnar single crystals are often white, and hexagonal crystalline graphite is common in meteorites with tabular single crystals. Lunar meteorites have the characteristics of breccia plagioclase, which is an important scientific basis for confirming lunar meteorites.

Lunar meteorites are rocks that were splashed out of the moon by an asteroid impact and fell to the earth, and are important objects for studying the material composition and evolutionary history of the moon. With the exception of a few rock types with crystalline structures, most of the lunar meteorites are clastic rocks, and there are three main types of clastic rocks: highland plagioclase breccia, lunar sea basaltic breccia, and highland plagioclase-lunar sea basalt mixed breccia.

When a large asteroid body or comet hits the surface of the Moon, the ejection of material on its surface can reach the speed of escaping the Moon (thus entering the universe, part of which is captured by the Earth and landed on the Earth, which indicates that the lunar meteorite is closely related to the impact crater event on the surface of the Moon, especially the low-angle impact of the large asteroid body is more conducive to the escape of the ejected material. Because the moon has undergone magmatic differentiation, lunar meteorites are chondrites.

The moon meteorite is composed of black crusts, caves, and air marks.
