The Earth's oldest rock is taken on the moon by the astronauts of Apollo 14 FOUR MILLIONS years after the great influence of the asteroid.
- The Moon sample was taken to Earth by astronauts during the mission of Apollo 14
- The analysis of the rock has proven to be 4 billion years old and may be on Earth
- A 2-gram fragment is composed of materials that are extremely unusual on the moon
The oldest rock on Earth may have been discovered and taken from the astronauts of the Moon during Apollo 14 in 1971.
The Moon sample was returned to Earth for further analysis after the astronauts assembled it during the third mission of the moon.
Now, 48 years later, experts claim that this relic was once part of the Earth after being on the Moon after a big comet or an asteroid collided with the planet.

The Earth's oldest rock may have been discovered and was taken by the astronauts of the Moon during Apollo 14 in 1971.
NASA researchers believe the impact of the collision throws the rock into space and then lands on the surface of the moon.
At that time the moon was three times closer to Earth than it is now.
Subsequently, the scale is mixed with other lunar surface materials in a rock fragment.

It partially melted 3.9 billion years ago, which buried it below the surface.
About 26 million years ago, an asteroid struck the moon and created the crater of the cone.
Researchers believe that this impact has helped to return the piece Earth to the surface of the Moon.
"This is an extraordinary discovery that helps to draw a better picture of the early Earth and the bombings that changed our planet during the dawn of life," said NASA scientist David Kring, who led the study.

Experts have found that the moon rock is formed at temperatures similar to those found on Earth today.
It crystallized about 12.4 miles below the surface between 4 billion and 4.1 billion years when the Earth was young.
The team identifies materials from the Earth after they have developed techniques for locating fragments of impact in the lunar soil.
They found that the 2-gram fragment of rock was composed of quartz, feldspar and zircon, all common on Earth and "highly unusual" on the moon.
It is necessary to form the sample at great depths, in the lunar mantle where various rock compositions are discovered.

WHAT ARE THE THEORIES OF THE MUNICIPAL ORIGIN?
Many researchers believe that the moon formed after the Earth was hit by the Mars-sized planet billions of years ago.
This is called the hypothesis of gigantic impact.
The theory suggests that the Moon is composed of remnants left after a collision between our planet and body about 4.5 billion years ago.
The confrontational body is sometimes called Thea after the mythical Greek Titan, who is the mother of Selena, the goddess of the moon.

But a mystery has survived, revealed by the rocks that Apollo astronauts have returned from the moon: Why is the Moon and Earth so similar in its composition?
Several different theories have emerged over the years to explain similar prints on Earth and Moon.
Perhaps the impact has created a huge cloud of debris that completely blends with the Earth and then condenses to form the moon.
Or Theia could, by accident, be chemically similar to the young Earth.
A third possibility is that the moon is formed from earth materials rather than from Thea, although this would be a very unusual type of impact.
