What are planets of Solar system amazing by?

The Wandering star . The word the planet is so translated from Greek. Planets do not take a certain place in the star sky, and wander among stars. It occurs because that they rotate around the Sun. Most closer Mercury is located to the Sun. In 88 terrestrial days it makes a revolution around the Sun.

Even by the light of the Sun, in beams of a morning and evening dawn when other stars already disappeared, in the sky it is possible to make out a bright star. But, alas, it is not a star. The planet reflects a sunlight. Therefore it seems the shining sphere. This planet was called in honor of the goddess Venus. Invisible radio beams helped to know the planet better. On it there are a plain and two mountain chains. On its surface volcanoes meet huge craters and a firm lava. From Earth only one party of Venus is visible.

It turned out that it is lazy. If Earth manages to turn back 117 times, then Venus round its pivot-center - only once. On Venus, as well as on Mars, there is no winter, spring, fall. All the year round the summer reigns. But do not dream to go to sunbathe there! Such metals as tin and lead, it would be possible to scoop buckets there as water from a well. All water evaporated long ago. Only stone plains decorate Venus. Nevertheless, scientists dream to see the planet with own eyes.

The earth - the third planet of Solar system. It is the only planet still known to us on which there is life. Live the cover of the planet is formed by microorganisms, plants, animals, people.

If in the night sky you notice a reddish asterisk which winks at you, then know - it is our closest neighbor - the planet Mars. When scientists photographed this planet, it turned out that the Martian earth it is reddish - brown color, and the sky is dim - pink of - for parts of reddish dust. Dust lies a thick layer at the bottom of craters, on slopes of mountains, in valleys and deep ravines. Once wind rises, the dust storm begins. It lasts several months. Then dust accumulates, the sky clears up. Mars calms down.

Mars is less than Earth approximately twice, and is 1,5 times further from the Sun. Therefore receives less heat from the Sun. In the afternoon here it is possible to sunbathe, but with sunset sharply becomes cold. Strikes a frost at night. But neither the bathing suit, nor a fur coat will be necessary for you for travel on this planet! Its atmosphere is unsuitable for breath.

Brightly - a white star Jupiter shines in a firmament. It is the major planet of Solar system. Its diameter is about 140 thousand km. Year of Jupiter is equal to nearly 12 terrestrial years. This planet is rich in satellites. If Earth only one natural satellite - the Moon, then at Jupiter has their more than ten. And four of them are comparable with Mercury and the Moon. Feature of this planet is that on it there are no sushi. Continuous ocean Only it is not clear where air comes to an end and begins ocean . Only the ocean hot though the planet is located far from the Sun.

Jupiter is followed by Saturn. It is surrounded with magnificent flat rings which make as if one ring. In it it is possible to lay three times the globe. A ring of Saturn not continuous, it consists of the small satellites located in one plane.

Jupiter and Saturn - planets - giants. They consist generally of hydrogen and helium. In 1781 the new planet which more Earth by 73 times was opened by Gershwin. It is Uranium. The French scientist Leverye found out that in 60 years the planet deviated the calculated orbit. The scientist assumed that Uranium is attracted by other, still unknown planet, and specified its place. There was also a planet the Neptune called in honor of antique god. At supervision in the telescope the planet has an appearance of the greenish disk deprived of any details. There is no wonder. The planet is removed from the Sun on 4,5 billion kilometers.

Pluto was considered as the smallest planet. Perhaps, from - for the size she had to leave the list of planets. In Solar system there are a lot of minor planets with a diameter from several hundred meters to hundreds of kilometers. They are called asteroids. So our scientists have an opportunity for opening of new planets.
