Planets (Planets) star planet means that there is no light in itself. But reflect sunlight into the eyes of our planet and its moons are not equal. Stay away from the sun Distance differ, and the difference was in the solar system. By rotating around its own orbit. Sun Speed varies from study about planets, using the world's major share in the planet. There is a star in its own light. Unlike the sun or the stars, which shine on their own. But we can see planets. Because of the planet Reflected light from the Sun. Access our eyes that even the planets in our solar system are the eight planets (including Earth), but we can see with the naked eye, only five planets, only Mercury, Venus, Mars, Jupiter and stars. The ancients called Saturday only Planet of the five that "The Wandering Stars" or "Planetes" in Greek, and the sun and moon and two planets that "The Two Great Lights" which when combined total of seven satellites will be the source of a day in the first. week that the eight planets can be divided into groups as follows: 1. physical by nature - the inner planets (Inner or Terrestrial Planets): a group of planets. That is closer to the sun than the other group. As the planet cools over. The solid surface Like Earth, our so-called Terrestrial Planets (meaning "earth") and Mercury (Mercury), Venus (Venus), the world (Earth) and Mars (Mars), which will take the band. Asteroids (Asteroid Belt) is the median - the outer planets (Outer or Jovian Planets): to be a planet. The sun is far more than other groups. The newfound planet is cooling The outer surface The gas is mostly covered with a surface of Jupiter. It is called Jovian Planets (Jovian comes from the Jupiter-like means like Jupiter) and Jupiter (Jupiter), Saturn (Saturn), Uranus (Uranus), Neptune (Neptune) image display period. The average The outer planets Light Hours of sun by the mean duration of exposure. From the Sun The planets (In hours) and Astronomical Units represents the distance in astronomical units (AU) divided by 2. The path is as follows: - inner planets (Interior planets) represents the closest planet to the Sun than the planet Mercury, and Venus. - outer planet (Superior planets) means the world to the next planet, namely Mars, Jupiter, Saturn, Uranus, Neptune 3 divided by the surface - the planet Mercury, Venus, Earth, rocks and Mars both. 4 The surface is hard as a rock. A thin layer of atmosphere enveloped except the perihelion of Mercury has no atmosphere - planets including Jupiter, Saturn, Uranus and Neptune are gas across the sun. There may be a small rocky core inside surface is covered by atmospheric methane, ammonia, hydrogen and helium (for Pluto is still inconclusive whether any of them. Because of the distance from Earth), except that we know. The planet rotates around its own Orbit around the Sun Valley Marriott ago. Each planet has tilted axis (the vertical movement) does not equal addition, compared direction. The Rotation The rotation around the sun Each of the planet Venus (Venus), Uranus (Uranus) to rotate around itself. Different from other planets. In our solar system
