Super Moon Live Broadcast
Each of us has our closest friends in life. They will always be by your side when you are sad. The earth also has a close good friend who has always been by its side, and it is the moon. Today, the editor will take you to understand it.
Overview of the Moon
The moon is what we see with the naked eye. When the weather is good, we can see it almost every day. As the natural satellite of the earth, the moon is the most loyal guardian of the earth. Humanity's exploration of the universe first began with the moon. So far, it is the most studied celestial body by humans.
The average distance between the moon and the earth is about 380,000 kilometers. How far is this distance? The editor can give an example to illustrate: If we walk towards the moon, walking 5 kilometers per hour, day and night, it will take more than 3,000 days, nearly 9 years, to cover this distance. This is the distance between the moon and Our average distance.
The moon is very small compared to the earth, and its volume is equivalent to 1/49 of the earth's volume. In other words, 49 moons come together to form a sphere as big as the earth.
The surface of the moon
When we look up at the moon, we will see that there are light and dark colors on the moon's surface. The ancients thought about it. Based on these light and dark outlines, they imagined patterns of various shapes, which formed some beautiful myths. . It was not until 1609, after Galileo viewed the moon through a telescope, that he revealed the mystery of the moon's surface. It turns out that the moon's surface is not so perfect. It is "pockmarked" and covered with large and small craters, also known as "lunar craters". There is neither a sweet-scented osmanthus tree nor a Chang'e and a Jade Rabbit on the moon. Those light and dark patches are just rugged mountains and plains.
In addition to mountains and plains, the most striking scenery on the moon is the crater just mentioned. The largest crater is near the Antarctic, called Bailey Crater. Its diameter is 295 kilometers, which is larger than my country's Hainan Island.
Another view on the moon is the lunar sea. Don't be fooled by the name. It is not an ocean, it is a vast plain on the moon. The largest lunar sea is called "Ocean Procellarum", covering an area of about 5 million square kilometers, which is equivalent to 9 times the area of France. The parts of the lunar sea extending to the lunar continent are called "bays" and "marshes", such as Dew Bay, Hongwan, Mengmarsh, etc. Their names are very poetic. The landing area chosen for the first stop of China's lunar exploration was the Hongwan area.
The unique world of the moon
After understanding the size of the moon and the characteristics of its surface, the editor finally takes you to experience the unique world of the moon. Since there is no atmosphere and water on the moon, there is no weather change, and you never have to worry about wind or rain. In addition, we know that sound is transmitted by the atmosphere. There is no atmosphere on the moon, so you can’t hear anything. Even if someone shouts in your ear, you don’t have to worry about hearing damage. It is a very quiet place. world.
What’s more interesting is that the gravity on the moon’s surface is much smaller than that of the earth, only one-sixth of the earth’s gravity. For example, a person who weighs 60 kilograms will feel that he is extremely powerful when he goes to the moon. He can lift 50 kilograms on the earth, but he can lift 300 kilograms on the moon. Who on earth can lift 300 kilograms? However, it is a piece of cake on the moon.
