Earth has only one natural satellite, the Moon. According to information from the International Astronomical Union (IAU), there are more than 160 Moons in the solar system.
Planet Earth's Moon has a diameter of approximately 3,476 kilometers, being 80 times smaller than our planet. Its distance to Earth can range from 356,800 kilometers to 406,400 kilometers.
Just like the Earth, the Moon does not remain static either, therefore making some movements. The three main ones are rotation (displacement around its own axis), translation (displacement around its axis). Sun) and revolution around the Earth.
Apollo XI Mission
The Moon has always been the object of much curiosity among human beings. So much so that on July 20, 1969, three US astronauts (Edwin Aldrin Jr., Neil Armstrong and Michael Collins), crew members of the Apollo XI spacecraft, hit the Moon.
This mission was marked by the following sentence by Neil Armstrong: “This is a small step for man, but a big leap for humanity.”
Other missions in order to obtain more information about the Earth's natural satellite continue to be carried out. The last significant discovery was the existence of water molecules on the Moon.
