There is a special connection between astronomy and mathematics, because astronomical predictions are the result of rigorous calculations. In fact, many problems in astronomy have become possible to solve thanks to the development of new branches of mathematics. From this book, the reader will learn about how the position of celestial bodies and the distance between them is measured, as well as about astronomical phenomena during which space objects occupy a special position in space.
