Earth’s conditions are related to many other forces in nature, for example, the levels of radiation emitted by the Sun. The moon is also an important part of the Earth’s work. Not surprisingly, the Moon’s natural gravity generates a phenomenon known as tidal force, which causes the movement of the planet and, consequently, in different regions of the oceans.
For a long time humans had no idea about this That the Moon was slowly moving away from EarthFor this reason they based much of the concept of the month in lunar movement. After all, when looking at the sky with the naked eye, it is impossible to notice any significant changes.
According to information collected by scientists, the orbits of the Moon and the Earth have been slowly moving away from each other for a long time. From data discovered by the Lunar Laser Ranging (LLR) experiment, It is possible to have an accurate idea that a natural satellite is moving at a rate of 3.8 centimeters per year.
To explain more about the fixed distance between the Moon and Earth, TecMundo has collected information from experts and scientists in this field. paying off!
The moon is moving away from the Earth
One of the most popular theories is that the Moon appeared after a collision between the celestial body Theia and Earth, about 4.5 million years ago. After the collision, a large amount of material from our planet was launched into space and then went through a gravitational process that brought all of this material together and formed the wonderful natural moon.
In addition to the formation of the Moon, gravity is largely responsible for the annual distance of 3.8 cm. Due to the force of lunar gravity, the Earth suffers from bulges that upset its balance and slow down its rotation.; In this way, our planet loses energy and angular momentum, resulting in slow motion away from the Moon.
Distance from the Moon can also affect day length dynamics; for example, scientists have already estimated that the Earth experienced a 19-hour day about two billion years ago.source: Getty Images
In other words, the faster the rotation speed, the greater the angular momentum responsible for the phenomenon of gravitational interaction between the Earth and the Moon. The slower it is, the smaller the angular momentum. To maintain this angular momentum, the satellite needs to move away from our planet.
“It’s not just the rate of rotation that affects angular momentum. It’s also important how far you are from the center of the system. Furthermore, it means the angular momentum of the system increases. Closer means your angular momentum decreases. As the Earth’s rotation slows down, in order for Angular momentum. Something must increase the angular momentum of the system. What increases angular momentum? “An object in orbit like the Moon is moving away,” UC Santa Cruz astrophysicist Madeleine Broome said in a message to the site. Live sciences.
However, it is important to note that humanity will probably not have any problems related to the distance from the Moon; The satellite will not be completely clear of our orbit. The most likely ending to everything is for our Sun to turn into a red giant and swallow the Moon and Earth together.
