With this small excursion to the field of space physics, the author, in addition to a direct task, pursues another goal. He would like to dispel to some extent the prejudice existing in the public against celestial mechanics and physics, as knowledge too abstract, unable to give food to the living mind. Science, which opens up the possibility of successfully competing in the flight of imagination with the imagination of the wittiest novelists, to test and correct their bold designs, science, indicating the ways of realizing the greatest dreams of mankind, should cease to seem dry and boring. The author hopes that the simplest information from this field of knowledge, which are scattered in this book, will instill in the mind of an inquisitive reader an interest in the study of the mechanics and physics of the universe and arouse the desire to get acquainted with the foundation of the majestic science of the sky.
