Features of the moon
Features of the moon – The moon is the only moon on Earth and its closest neighbor. This beautiful and bright sphere in the sky has interesting features; For this reason, in this article, we want to introduce the most unique features of the moon. In addition to its mesmerizing glow in the sky, the moon has other interesting features that you may have heard less of. According to the prevailing theory, the moon formed shortly after the formation of the solar system about 4.5 billion years ago when it hit a rock the size of Mars and became the only moon on our planet.
1. There is no semi-dark moon!
One of the most interesting features of the moon is that we always see only one side of its face. This is very interesting as the moon and the earth both revolve around themselves and the sun. Long ago, the Earth’s gravitational pull caused the moon to rotate more slowly around its axis, and this went so far as to adapt to the moon’s rotation around the sun and stabilize it in some way. Of course, this feature is not limited to the lunar sphere, and many of the other planets’ moons exhibit similar behavior. The earth is located. In fact, contrary to popular belief, the moon does not have a dark side, but a half that we will never see.
2. The moon will have a sister in the future
The moon is currently the only moon on Earth, but it probably won’t stay that way forever. Scientists and astronomers discovered in 1999 that a 5-kilometer-wide meteorite was moving in Earth orbit and was likely to be caught in Earth orbit by the gravitational pull of our planet. Cruithne is placed on it, to be in a horseshoe orbit around the earth for another 770 years, and will remain in this orbit for 5,000 years, becoming the sister of the moon and the second moon of the earth.
3. Holes in the surface of the moon
The surface of the moon is full of holes created by severe collisions of celestial bodies between 4.1 and 3.8 billion years ago, and the wounds from these collisions are now seen as numerous holes on the surface of the sphere. These holes have not eroded much during this period for two reasons. First, the moon is not geologically active, and earthquakes, volcanoes, and the formation of mountains on the planet do not destroy its surface as much as the earth. The second reason is that the moon has no atmosphere and no wind or rain. For this reason, the holes on the surface of the moon have not changed much over the years.
4. The moon is not round!
Contrary to popular belief, the moon is not round or spherical but in the shape of an egg. One of the strangest features of the moon is that the moon’s core is not exactly at its geometric center and is about two kilometers away from the planet’s geometric center. Scientists believe that the moon’s core is most likely hot and molten, just like the Earth’s core. However, data from the NASA spacecraft in 1999 showed that the lunar core makes up 2 to 4 percent of its mass; The Earth’s core, meanwhile, accounts for 30 percent of its mass.
5. Is the moon a planet?
The moon is larger than Pluto and about a quarter the diameter of Earth. Scientists believe that the moon is more like a planet, which is why they consider the earth and the moon together as a planet. This is called “two planets”. Pluto and its moon, Charon, are a “two planet” like the earth and the moon.
6. The effect of the moon on the earth’s tides
The moon, along with the sun, has a great influence on the earth’s tides. The moon’s gravity pulls the earth’s oceans toward it. The peak of sea tide occurs when the ocean orbits the moon at the same time as the earth rotates. Another peak of sea urchin occurs on the other side of the earth; The moon’s chute pulls the earth more than it draws water to itself, and that is why fashion happens. Strong tides occur during the formation of the new moon and the full moon; Because the sun, the earth, and the moon are in the same direction, and when the moon is closest to the earth, the strongest tides are formed. The slightest and most minor tides also occur in the beginning and end quarters of each month. There is another interesting reason for these tensions; Every year, some of the Earth’s rotational energy is stolen by the moon, slowing the Earth’s rotation by 1.5 milliseconds per century.
7. The moon moves away from the earth
Another feature of the moon is its distance from the earth. Each year, the moon takes some of the Earth’s rotational energy and uses it to enlarge its orbit. Because of this, the Earth’s moon moves about 3.8 centimeters away from our planet every year. Researchers believe that the moon was about 22,530 kilometers from Earth at the time of its formation, but this distance has now reached about 385,000 kilometers.
The sphere of the moon has 27% of the diameter and 60% of the mass of this planet, as a result of which the mass of the moon is 81.1 of the planet Earth and among the known moons of the solar system, it is the second heaviest moon after Jupiter. The reason for the uniqueness of the moon compared to other satellites of the solar system is the strong gravitational pull of the moon and the sun relative to the moon and the earth. That is why its path is always curved towards the sun. The moon is the most visible cosmic object to be observed from Earth. The phases of the moon and its orbit are still a mystery to many because the moon orbits the earth in both orbits for 27.3 days, so the earth’s inhabitants always see one side of the silver sphere. The moon is seen in the dark of night because it reflects sunlight, and the amount of surface seen from the moon depends on its position relative to the earth and the sun. Although the moon is the earth, it is larger than the planet Pluto. Some scientists consider it a planet, even though there are four moons larger than the moon in the solar system, yet no one has officially identified the moon as a planet.
