The information about the moon is different and diverse because it talks about everything related to the moon in terms of its definition, elements, rotation and the beginning of its existence, apart from being on the earth and the sun, and it increases the general culture of man and about its phases, shape and elements and lunar eclipses. Important information to talk about.
Which planet is the moon of earth?
According to astronomers, unlike other planets that have more than one planet, it is the only natural moon that follows the planet Earth. For that, the diameter of the Moon is a quarter of the diameter of the Earth and the natural Moon. Although the surface of the Moon is dark and transparent, it is considered the brightest thing in the sky after the Sun. And next day we will talk about the distance between the Moon and the Earth.
How far is the moon from earth?
The distance between the Moon and the Earth is between 364,397 km and 4,063,131 km, and as the Moon orbits the Earth, it takes about 27.3 days to complete one complete revolution around the Earth, which is about the same period. Time for the moon to wrap around itself.
Information about the Moon
After defining Earth’s moon, we refer to the following collection of information about the moon, which is a statement of proven scientific facts:
- The width of the moon is about 3475 km.
- The Moon’s surface is full of craters caused by meteorite impacts millions of years ago, and the South Pole Basin on the Moon is the largest crater on its surface, 2500 km wide and 8 km deep. .
- The moon shines by taking its light from many angles of sunlight, so it’s basically dark and dim.
- The time taken by the Moon to orbit the Earth and the time it takes to orbit itself is 27.3 days.
- Actually, the moon is elliptical, not round or spherical.
- There are more than 500,000 craters on the moon’s surface, with the south pole being the largest.
- The size of the Moon is 27% that of Earth, and it is the largest natural satellite in the Solar System in proportion to its size and the size of the planets that follow it.
- The moon does not revolve around the sun, but it revolves around the earth, which revolves around the sun.
- The moon has been a way for people to know months and times for thousands of years, and is still a way to determine months in the Hijri calendar today.
- The speed of the Moon in its orbit around the Earth is 3,700 kilometers per hour.
How is the moon?
There are many theories about the origin of the Moon, perhaps the most accepted of these theories is the giant impact theory, and this theory states that a large celestial body, the size of Mars, collided with the Earth and was recent. . The moon formed from it, this theory implies that these large and massive collisions were natural at the beginning of the formation of the solar system, and the evidence for this theory consists of meteorites very similar to the formation of the present day moon. Rocks on the surface of Mars.
What are the elements of moon?
The moon is mainly composed of three types, these three categories are:
It is the smallest iron core and is the deepest structure of any planet or body in the solar system, and this core is 680 km wide and the most important iron metal because it contains a high percentage of sulfur. as well as
It is the layer between the inner core and the thin surface crust. It is the name of the layers that make up the Moon. Its thickness is about 1330 km. It is a large group of rocks containing many minerals such as iron. .
Kind of east
It is the last crust on the surface of the Moon, and the depth of this crust is only about 70 km, its outer surface is the visible surface of the Moon, which is full of large holes as a result of the collision of various celestial bodies. . With the moon for millions of years.
What are the phases of the moon?
Moon passes through eight phases in each city, these phases are:
- Dor al-Muhaq: The moon is always known by sight.
- Like a crescent moon: A person can see the moon this way, but soon after the sun has set and at a low point in the sky.
- Al-Darbi Al-Darbi: It begins this way after the first week of the month, and half of the moon is visible only during the first half of the night.
- Torr Humpback: This is the most visible shape of the Moon.
- Full Moon Shape: This is the shape it appears in full moon light and the moon can be seen in this shape from nightfall to sunrise.
- Opposite form: Since the moon continues to appear until sunrise, this is the form where the moon cannot be seen even after midnight.
- Al-Darbi Al-Ashti: This is the half-illuminated form of the moon, and it appears only in the morning or during the day, and it disappears completely at night.
- Crescent Shape: This is the shape in which the moon begins to turn into a crescent shape, except in the early morning when a small portion of the moon is visible.
What is on the surface of the moon?
The surface of the Moon contains a rocky debris known as regolith, which is a rock exhumed from volcanic craters on the surface of the Moon, and the surface of the Moon consists of the following physical and chemical elements and components:
- 43% oxygen.
- 20% silicone.
- 19% magnesium.
- 10% iron.
- 3% calcium.
- 3% aluminum.
- 0.42% chromium.
- 0.18% titanium.
- 0.12% manganese.
Astronomers knew that the Moon was a celestial body that revolved around the Earth rather than the Sun.
Why it matters: Why does a lunar eclipse happen when it’s bad?
Strange facts about the moon
Among the strange facts about the moon are the following:
- The Moon’s gravity is much weaker than Earth’s, so weights are lighter on the Moon than on Earth; Because of its small mass.
- In fact, all of the people who walked on the moon were Americans, 12 of whom were astronauts.
- Eugene Cernan was the last to walk on the moon during the Apollo 17 mission in 1972.
- The Moon’s temperature varies greatly because it lacks a special atmosphere and is constantly exposed to varying winds and solar radiation.
- Earthquakes constantly hit the surface of the moon due to the gravitational force of the moon, and these earthquakes lead to many cracks and fissures in the surface.
- Humans cannot hear sounds on the surface of the moon because it has no atmosphere.
- The Moon is gradually moving away from Earth, so every year the date moves 3.8 cm away from Earth, and scientists believe this will continue for the next 50 billion years.
- The mass of the Moon is 1/8 of the total mass of the Earth.
Moon facts for kids
Among the most important information about the Moon for children are the following:
- The Moon orbits the Earth in a circular motion once per lunar city.
- The Moon is the only celestial body that orbits the Earth.
- The first spacecraft to land on the moon was a Soviet spacecraft.
- A total eclipse of the Earth occurs when the Earth is between the Moon and the Sun.
- Walking on the Moon is like a long jump due to the weakness of gravity.
- Light from the moon takes 1 second to reach the earth’s surface.
- The Moon takes four weeks to complete one complete revolution around the Earth.
What is a lunar eclipse?
A lunar eclipse is an astronomical event in which the Earth blocks the light emitted from the Sun to the Moon.
- Total Eclipse: This eclipse occurs when the Moon is completely in the Earth’s shadow, resulting in loss of vision even in the middle of the night.
- Partial Eclipse: This eclipse occurs when a part of the Moon is in the Earth’s shadow.
- A penumbral eclipse: An eclipse occurs when the moon falls in a region called the penumbra, and in this eclipse the moonlight is intense and does not disappear completely.
With this information, we have reached the end of this article by talking about the information about the moon and also about the origin of the moon and its elements.
