solar system - is 8 large celestial bodies, and numerous moons, comets and asteroids.People interested in astronomy since time immemorial.Then the sages were trying to determine the fate of star man to predict future events.Even with the naked eye can see five planets, so the composition of the solar system in those days was as follows: Venus, Mercury, Mars, Saturn and Jupiter.
Only with the advent of telescopes, scientists were able to examine in more detail the structure of the known celestial bodies and see the remote and previously unknown planet.The launch of the first space station has turned many people's ideas and in a new light revealed a planet of the Solar System.For children it is very interesting and informative this issue because small "pochemuchek" attracts the unknown.
closest to the Sun is lowest in the celestial body - Mercury.It can still be called a "planet of contrasts", as one side is melted by the heat of 300 degrees, and the other cold and darkness reigns.This is for the reason that Mercury revolves around the sun quickly and very slowly on its axis.Companions had not.
researchers have a lot of mess, until they are able to explore Venus.This mysterious planet is shrouded in a 20-kilometer layer of clouds, which is a hell, because the surface of a celestial body is red-hot 500 degrees.Due to continuous nebula sun's rays do not penetrate here, so on Venus reigns gloom.The atmosphere consists of carbon dioxide, sulfur are constant rains and the wind at high speed chase clouds.
Mars gained fame as the most popular of the planet of the solar system.For children there is a lot of well-known science fiction books of the last century, who believed that here, too, there is life.This celestial body really is a bit like the Earth, here last night a little more than 24 hours, the axis position is very similar to the axis of the planet.But life on Mars is still not detected, the atmosphere is too rarefied, it is heated by the sun is bad, so is the temperature does not exceed 0 degrees.
to giant planets are Saturn, Jupiter, Neptune and Uranus.Jupiter gained fame as the biggest planet of the solar system.For children to be interested in what he is rotating at high speed, in its atmosphere, visible only to quickly passing clouds.Heavenly body has a very strong magnetic field.It has 16 known moons.
Saturn is composed of hydrogen and helium, it is cold, swift winds known.Most interesting is the system of rings encircling the celestial body.Until now, scientists have not found an explanation to them, and they have accumulated more questions than answers.It has 15 known moons.
Uranus and Neptune also giants, but the ice rather than gas.The first has a very monotonous surface, gathered near her 5 satellites.The second resembles the Earth because of the deep blue.As the wind speed to compete with Neptune can not no planets in the solar system.For children, even a secret that was considered a planet, and Pluto, but then it was decided to exclude it from the list and be considered a dwarf celestial bodies, which is what about 50 planets.
