Which is older Moon or Earth and how old is the Moon?

The moon is large, and studies have shown that the earth's rocks are at most 4.5 billion years old, and some of the moon's rocks are 5 billion years old, and the moon is actually the earth's companion star.

Xinhuanet Berlin, November 25 (Reporter Liu Xiang) According to the American magazine "Science" 25**, German and British scientists have recently measured that the moon was formed 4.527 billion years ago, only about 30 million to 50 million years later than the solar system. This is the most accurate measurement of the Moon's age to date.

Scientists have determined that the age of the Earth is 4.6 billion years old.

So the Moon is about 45 27 years old and the Earth is 4.6 billion years old. The age of the earth is large.

Question answers. German and British scientists have recently accurately measured the age of the moon to be 100 million years old.

According to the latest measurements by German and British scientists, the Moon was created 100 million years ago, only about 30 million to 50 million years later than the solar system. This is the most accurate measurement of the Moon's age to date.

Researchers from the University of Münster in Germany, the University of Cologne and the University of Oxford in the United Kingdom reportedly arrived at this result by analyzing specific metals in different samples of lunar rocks brought back by the American Apollo spacecraft.

The researchers analyzed the amount of tungsten-182 isotopes in lunar rocks, which are partly produced by the decay of radioactive hafnium-182, which decays very quickly by geological standards. The amount of tungsten-182 is able to give relatively accurate information about the age of the rock.

Previous estimates of the Moon's age have been based on imprecise date data on some lunar rocks, and have only determined that the Moon should have been created within 100 million years of the birth of the solar system. The latest research yields a margin of error of only about 10 million years for the age of the moon.

Experts say that this data is in line with the currently commonly used theory of the creation of the moon, and also supports the theory of the time of the formation of the earth.

Experts emphasize that this new understanding will also contribute to the study of the history of the Earth's production. According to the usual theory of the Great Collision, the Earth's predecessor, the so-called "Proto Earth", collided with a Mars-like star, resulting in fragments forming a disk that revolved around the Earth, which eventually coalesced to form the Moon. This massive collision most likely marked the end of the Earth's formation process.

To date, it has not been possible to date the Earth definitively, because the oldest rocks on Earth are at least 500 million years younger than the Earth, and it is not feasible to use them to determine the age of the Earth. According to the theory of the Great Collision, the creation of the moon occurred at the same time as the formation of the earth, so knowledge about the creation of the moon may give the answer to the birthday of the earth.

The Moon is larger, although it is the gravitational pull of the Earth that attracts the Moon to it.

The Earth's Great Moon was formed after the formation of the Earth, according to scientists.

They formed around the same time, and when the Earth was first formed, it was very unstable, and the Moon may have detached from the Earth. It is also possible that it was formed independently, and it should not be possible to say which one is earlier.

Scientists in Germany and Britain have recently accurately measured the age of the moon at about 4.6 billion years. As long as the ratio of the isotope content in the rock before and after decay is measured, its age can be deduced from the known half-life. This method measures the "radioactive age" of the rock, which is used as the age of the Earth.

The meteorite material is small in size, the internal force has very little effect on its transformation, it has not been melted and differentiated many times, and the cumulative effect on various nuclear transformation energies is small, so it is very reasonable to take the age of the meteorite as the representative age of the earth and the moon. The isotopic ages of Moon, Earth, and meteorite materials have been determined by various methods, all of which are very close to each other, about (100 million years. As a result, it is generally believed that both the Moon and the Earth were formed 4.6 billion years ago.

In fact, radioisotope methods measure the age of the Earth's crust when the rocks solidify from the scorching molten magma, long before the Earth was born. It has been pointed out that "the Earth was formed between fifty and fifty-five billion years ago as an independent planet in the solar system" (Sha Jingeng:

Ancient and vibrant paleontology", published in Science, No. 1, 2002).

The moon is older.

The age is the time when a solid surface is formed, with the oldest rocks on Earth being 4.6 billion years old and the oldest rocks on the Moon being 5 billion years old.

The age of the Moon and the Earth is about the same, about 4.6 billion years old.

The Moon is older than the Earth.

The average age of the Earth is 4.6 billion years, the average age of the Moon is 4.5 billion years, but the rocks in some areas are more than 5 billion years old. This negates the claim that the Moon and the Earth were born at the same time.

Earth, the mainstream theory of the formation of the Earth-Moon system is the Great Collision Theory: a Mars-sized celestial body (known as Thea, the mother of the mythical lunar goddess Selene) collided with the original Earth, and the burst material entered the orbit around the Earth and formed the Moon through accretion.

It stands to reason that it is the same size. Because it is a fragment of two stars when they collide, they are formed by gravitational condensation.
