Solar system consists of four smaller inner planets: mercury, Venus, Earth and Mars, also called the planets of the earth group, composed mainly of silicates and metals. The four outer planets: Jupiter, Saturn, Uranus and Neptune, also called gas giants, largely composed of hydrogen and helium and is much more massive than the terrestrial planets.
Most large objects revolving around the Sun, moving almost in the same plane, called the Ecliptic. However, at the same time, comets and Kuiper belt often have more angles to this plane.
All the planets and most other objects revolve around the Sun in the same direction with the rotation of the Sun (counterclockwise when viewed from the North pole of the Sun). There are exceptions, such as Halley's comet. The largest angular velocity has a mercury - he manages to make a complete revolution around the Sun in just 88 earth days. But for the most distant planet - Neptune - circulation period is 165 earth years.
A large part of the planets rotated around its axis in the same direction that moves around the Sun. The exceptions are Venus and Uranus, and Uranus rotates almost lying on its side" (tilt axis about 90°).
Mercury is the closest planet to the Sun and the smallest planet system (0,055 Land mass). The mercury has no satellites, and its only known geological features, in addition to the impact craters are numerous jagged slopes, stretching for hundreds of miles - the escarpments.
Venus is similar in size to Earth (0,815 earth masses) and, like Earth, has a thick silicate shell around the iron core and the atmosphere. There is also evidence of internal geological activity. However, the amount of water on Venus is much smaller than the earth and its atmosphere in ninety times denser. Venus has no satellites. It is the hottest planet, its surface temperature exceeds 400 °C.
Mars is smaller than Earth and Venus (0,107 Land mass). It has an atmosphere consisting mainly of carbon dioxide. On its surface there are volcanoes, the largest of which, Olympus, exceed the size of all of earth's volcanoes, reaching a height of 21.2 km
Red surface of Mars due to the high amount of iron oxide in its soil. The planet has two satellites - Phobos and Deimos. It is assumed that they are captured asteroids
Asteroids are the most common small bodies of the Solar system.
Jupiter has a mass of at 318 Earth masses, which is 2.5 times more massive than all the other planets put together. It consists mainly of hydrogen and helium. Jupiter has 65 satellites. The four largest - Ganymede, Callisto, IO and Europa - similar to the planets of the earth group such phenomena as volcanic activity and internal heating.
Saturn, known for its extensive system of rings, is somewhat similar to Jupiter the structure of the atmosphere and magnetosphere. Although the size of Saturn is 60 % jupiterians, weight (95 Earth masses) - less than a third jupiterians; thus, Saturn is the least dense planet in the Solar system (its average density comparable to the density of water).
Saturn has 62 confirmed satellites; two of them - Titan and Enceladus - show signs of geological activity. The activity, however, is not similar to the earth, because largely due to the activity of ice. Titanium, surpassing the size of mercury, is the only satellite in the Solar system with a substantial atmosphere.
Uranium with a mass of 14 Earth masses is the easiest of the outer planets. Unique among the other planets it does what it is rotating "lying on its side". If other planets can be compared with rotating tops, Uranium is more like a rolling ball. He has a much cooler core than the other gas giants, and emits very little heat into space.
The Uranium are 27 satellites; the largest - Titania, Oberon, Umbriel, Ariel and Miranda.
Neptune, though a little less Uranium, more massive (17 Earth masses) and therefore more dense. It emits more internal heat, but not as much as Jupiter or Saturn.
The Neptune has 13 known satellites. The largest is Triton is geologically active, with geysers of liquid nitrogen. Triton is the only large satellite moving in the opposite direction. Also Neptune is accompanied by asteroids, called the Neptune Trojans.
Comets are small bodies of the Solar system, usually just a few kilometers, consisting mainly of volatile substances (ice).
The Kuiper belt - the region relics of the time of formation of the Solar system, which is a large belt of debris, similar to the asteroid belt, but consisting mainly of ice
