Since 2006, the title of the smallest planet Mercury has become worn.For scientists, it is of interest because of the unusual terrain of jagged slopes, dotted with the entire surface, and the period of rotation around its axis.It turns out that he is one-third less time to complete revolution around the sun.This is because of the strong tidal influence of light, which has slowed the natural rotation of Mercury.
second in distance from the center of attraction of Venus is famous for its "vehemence" - the temperature of its atmosphere even more than the previous object.The effect is due to its existing greenhouse system that emerged due to the increased density a
nd the predominance of carbon dioxide.
third planet - Earth - is the habitat of people, and yet it is the only one where precisely recorded the presence of life.It is something that is not present at the previous two - satellite called Luna joined her soon after the occurrence, and this momentous event occurred about 4.5 billion years ago.
most militant area of the solar system can be called Mars its red color due to the high percentage of soil iron oxide geologic activity over the whole 2 million years ago, and the two satellites were brought forcibly from among asteroids.
fifth of the distance from the Sun, but the first is the size of Jupiter, has an unusual history.It is believed that he had all the makings to turn into a brown dwarf - a small star, because the smallest of this category exceeds its diameter by only 30%.More than it is, the size of Jupiter do not get: if its mass is increased, it would under the influence of gravity to increase the density.
Saturn is the only one among all the others has a noticeable drive - belt Cassini, consisting of small objects surrounding him and debris.Like Jupiter, it belongs to a class of gas giants, but significantly inferior in density, not only him, but also the earth's water.Despite its "gaseous" Saturn has at one of its poles present the northern lights, and its atmosphere is raging hurricanes and storms.
Next on the list of Uranus, like its neighbor Neptune, belongs to the category of ice giants: its bowels contain a so-called "hot ice", from the usual featuring a high temperature, but do not turn into steam from the-this strong compression.In addition to the "cold" component, Uranus has a number of rocks, as well as the complex structure of clouds.
Closes list Neptune opened a very unusual way.Unlike other planets detected by visual observation, that is, a telescope and more complex optical devices, Neptune noticed immediately, but only because of the strange behavior of Uranus.Later, through complex calculations was located influence him of the mysterious object.
