    History of the Solar System

    Solar System

    The Solar System is a collection of some neighbors in space that exist within certain limits. This extraordinary system of celestial bodies includes: a star, 8 planets, 140 moons and many other objects, such as asteroids, comets, and also dwarf planets. In the very center of the Solar System, there is an average yellow star, which we call the Sun. Around her, already about five billion years, in eternal dance 8 planets circle, and also - other rotating bodies. The dimensions of the planets vary from small stone worlds to giants consisting of gas and ice. Around these planets, many moons rotate, ranging in size from rocky asteroids to planets with their own atmosphere.

    The structure of the solar system

    At the moment we know that the Solar system consists of the Sun, eight planets and their moons, as well as asteroids, comets, dwarf celestial bodies, the Kuiper belt and the Oort cloud. Eight planets, with the exception of Uranus, move around the sun in the same direction and the same plane, called the ecliptic plane.

    History of the Solar System

    For many centuries people looked at the night sky and reflected on the mysterious lights, trying to at least partially understand the essence of what is happening. Soon people noticed that some lights move through the sky along certain trajectories. These lights were called planets, which from the Greek language is translated as a wanderer. At the time when the concept of "planet" appeared in the scientific community, scientists believed that the earth is the center of the universe, therefore the planets were presented as divine messengers wandering through the celestial spaces. Many planets have received divine names - Mercury, Mars, Venus, Jupiter, Saturn.

    After the dense Middle Ages were replaced by the Renaissance, scientific paradigms underwent significant changes. People began to gradually come to the realization that all the same the planets are moving around the sun, and not around the earth. A huge contribution to the astronomy of this period was made by such scientists as Galileo, Copernicus and Kepler.

    With the invention of the telescope, scientists realized that our solar system has a much more complex structure than previously thought. Soon the moons of Jupiter, as well as the rings of Saturn, were discovered. Thus began a new era in the exploration of the cosmos.

    Armed with telescopes, scientists continued to explore the cosmos. Eventually, after lengthy research, Uranus, Neptune and the ninth planet of the solar system of Pluto were discovered. Later, thanks to more advanced technologies, the moons of Mars, Jupiter and Saturn were discovered. Already at the beginning of the 20th century, mankind was able to see in detail the planets of the solar system. A significant event in the world of astronomy was the sending of telescopes into outer space. Thanks to the program "Voyager", launched in 1977, was obtained extensive information about the planets of our solar system. At the end of the 20th century the planet Pluto was ranked among the dwarf planets. Thus, our solar system began to consist of eight planets instead of nine.
