How many moons revolve around the earth?

How many moons revolve around the Earth, the vast space that surrounds us, and despite all the scientific discoveries in the field of astronomy and the universe, it is still somewhat mysterious, due to the difficulty of our access to other worlds, and despite that, scientists were able to discover the planets And to identify the causes of the bodies and the moons that revolve around them, including the moons and the bodies that revolve around the Earth in which we live, and in our article today via the reference website, we will learn about the moons that revolve around our earth and what belongs to them. 

The moons of the solar system

The moons of the solar system are generally solid bodies, and few of them have an atmosphere, and scientists are likely that most of the planets’ moons were formed from gas and dust disks scattered around the planets in the early days of the solar system, and the moons, which are also called natural satellites, come in many shapes and sizes There are hundreds of moons in our solar system, even a few asteroids have small companion moons, and the number of moons surrounding the processions ranges from more than 75 moons, such as those orbiting Saturn, to planets that do not have any moons such as Mercury.

How many moons revolve around the earth?

The number of moons that revolve around the Earth is one, in addition to the possibility of the existence of temporary or honorary moons. As for the moon that revolves around the Earth, it is the one that we see clearly and is associated with the Hijri year, but there are also moons called honorary or temporary moons, and they are captured Two of these moons are known, as the small asteroid called 2006 RH120, which orbited the Earth for nine months in 2006 and 2007 AD, and the 2020 CD3 moon, another small asteroid that was observed Before flying away from Earth in March of 2020, after spending nearly three years in orbit, objects are revolving around the sun in the circumference of the Earth, and the two most popular are 2010 TK7 and 2020 XL5 known as Trojans.

Information about the moon

When the Earth first formed about 4.5 billion years ago, it had no moons, and it is believed that the proto-Earth collided with a Mars-sized object called Theia, which blew up much of its crust in orbit, and this debris eventually formed in the moon we know, and this is a scientific theory, but the moon as a scientific discovery, we have a lot of real information about it, including:

  • Size of the Moon: The diameter of the Earth's moon is 2159 miles, or 3474 km, which is about a quarter of the diameter of the Earth, and this means that the moon is about a quarter of the size of the Earth.
  • Layers of the Moon: It is somewhat similar to the three layers of the Earth, and according to what scientists have learned, it is very likely that the Moon has a very small core, and its width is 680 km, while the thickness of the rocky mantle of the Moon is about 1330 km, while the average depth of the crust that includes The surface of the moon is about 70 km.
  • Movement of the Moon: The Moon revolves around the Earth in an elliptical or elliptical orbit, and its actual rotation in the sky is about 72 and a half days, while what we see on Earth is 29 and a half days, due to the different angle of our view of the Moon between Earth and space.
  • Moonlight: Although we see the moon’s light reflected on the Earth, the moon is an opaque body, and the light we see is the reflection of the sun’s light from the moon to the earth, according to the arrangement of the sun, the earth and the moon about each other.
  • The Moon's Atmosphere: The Moon has a very thin atmosphere, and scientists have suggested that one of the sources of the Moon's atmosphere is the release of gases from the Moon's interior as a result of lunar earthquakes, or by external factors, such as the effect of sunlight, solar wind and micrometeorites that strike the Moon's surface.
  • Lunar Eclipse: It is a natural phenomenon that occurs as the Earth mediates between the Moon and the Sun during the Moon’s rotation around the Earth, which leads to blocking the sunlight that is reflected from the Moon to the Earth by the Earth’s shadow.

How many satellites orbit the earth

Two types of satellites revolve around the Earth, and the first type is natural satellites, which are natural bodies that are formed by cosmic events, and are attracted to the Earth’s orbit by the Earth’s gravity, but they quickly disappear on the horizon. It was mentioned in the Index of Objects Launched into Outer Space, issued by the United Nations Office for Outer Space Affairs, that approximately 6,542 satellites are orbiting the Earth as of January 1, 2021, of which 3,372 are active and 3,170 are inactive. According to UNOOSA, the total number of satellites launched into space was 7,389 individual satellites at the end of April 2021.

With this, we come to the end of our article, which was entitled the largest animal in the world, through which we got acquainted with the moons of the solar system and the number of natural and artificial satellites revolving around the Earth, as we learned all the information about the Earth's moon.
