Interesting facts about the moon

Do you know such interesting facts about the Moon?

The moon makes a complete revolution around the Earth in 27, 3 days. She is always turned to the Earth with one side. The far side of the moon was inaccessible to the human eye until 1959, when the Soviet spacecraft Luna-3 photographed it.

More than 500, 000 lunar craters can be seen through a powerful telescope. The largest of them is called Baie, its diameter is about 300 km, and the area is slightly larger than the area of ​​Scotland.

The dark spots visible with the naked eye on the lunar surface are called seas. They have no water, but millions of years ago they were filled with volcanic lava. Some of them are very large, for example, the Ocean of Storms is larger than the Mediterranean.

There is no air or water on the moon. Its soil is so dry that nothing can grow on it. However, scientists have found that plants can grow in samples of lunar soil delivered to Earth.

Unlike the surface of the Earth, which is constantly changing water by the action of water and wind, the lunar surface remains unchanged. The footprints left on the Moon by the Apollo astronauts will be visible for at least 10 million years.

Interestingly, earthquakes, called moonquakes, occur on the moon, but they are very weak compared to earthquakes. There are more than 3000 moonquakes every year, but their total energy is barely enough for a small fireworks display.

The average density of the moon is 3.34 g / cm3, a conclusion from the obtained astronomical data shows that the inner part of the moon is most likely a hollow, and not a homogeneous sphere.

The word Luna comes from the Proto-Slavic luna. This word has Indo-European origin - from the word louksna - "light".

The moon's orbit around the earth is an oval, not a circle, so the distance from the center of the earth to the center of the moon is constantly changing.

Every second the moon is moving away from us, expanding its orbit by 4 cm per year. Scientists say that when the moon was just formed (4.6 billion years ago), it was at a distance of 22, 530 km from the earth. Now this distance is more than 450, 000 km.

There is an echo on the moon. On November 20, 1969, the crew of the Apollo 12 spacecraft threw the lunar module onto the surface of the moon, and the noise from its impact on the surface provoked an artificial lunar earthquake. The consequences were unexpected after that, the moon rang like a bell for another hour.

The Earth's gravity forces the Moon to orbit the Earth. However, the gravity of the moon also affects the Earth, primarily the seas and oceans, causing tides. When the Moon is at its closest distance, its gravitational pull increases and the tides reach their highest level.

There are dubious companies selling sites on the moon. For just a few thousand dollars, the buyer receives a certificate of "ownership" of a certain area of ​​the moon's surface.

Interesting fact - the Moon can become a graveyard for the rich. Recently, a service for the rich has become available, such as a funeral on the moon. For a certain amount, your ashes will be scattered onto the surface of this planet. The first "lunar deceased" was comet researcher Eugene Shoemaker, NASA sent a reconnaissance satellite to the Moon with his ashes on board.
