Atmosphere of the Moon and Moon Space
Since the mass of the moon is negligible, the gas shell around it must be very rarefied, i.e. practically absent. The main components of the gas shell were hydrogen, helium,…

Solar System: Composition and Features

The Sun enters the Solar System, 9 large planets together with their 34 satellites, more than 100 thousand small planets (asteroids), about 10 to the 11th degree of comets, and also countless small, so-called meteor bodies (from 100 meters across to negligible dust particles ) The central position in the solar system is occupied by the sun. Its mass is approximately 750 times greater than the mass of all other bodies included in the system. The gravitational attraction of the sun is the main force that determines the movement of all the bodies of the solar system that revolve around it. The average distance from the Sun to the planet farthest from it is Pluto 39.5 AU, i.e. 6 billion kilometers, which is very small compared with the distances to the nearest stars. Only some comets are 100 thousand AU away from the Sun. and are exposed to the attraction of stars. Moving in the galaxy, the solar system from time to time flies through interstellar dust clouds. Due to the extreme discharged matter of these clouds, the immersion of the solar system in the cloud can occur only with a small absorption and scattering of sunlight. Continue reading

Star worlds
By the beginning of our century, the borders of the explored Universe had moved so far that they included the Galaxy. Many, if not all, then thought that this huge…
