Line 1: − {{Solarsystem}}+ − The Solar System is the [[Sun]] and all the objects in orbit around the sun.<ref>Freedman, Kaufmann: ''Universe'', 7th edition</ref> Objects orbiting the sun include planets, moons, asteroids, and comets.+ − + − + − A [[planet]] is defined as an object that orbits the [[sun]], is massive enough that its own gravity pulls it into a nearly round shape, and is dominant enough to clear away objects in its neighborhood. <ref>http://www.nasa.gov/vision/universe/solarsystem/planetsf-20060824.html</ref> There are 8 planets in the solar system. They are, in order of increasing distance from the sun:<ref>The third grade</ref>+ − *[[Mercury]]+ − *[[Venus]]+ − *[[Earth]] − *[[Mars]] − *[[Jupiter]] − *[[Saturn]] − *[[Uranus]] − *[[Neptune]] − − The first four planets are [[terrestrial planets]], the last 4 planets are [[jovian planets]]. Terrestrial planets are small in size, have high densities, and consist of rocky materials. Jovian planets are large in size, have low densities, and consist of gaseous materials. − − − A [[dwarf planet]] is an object that orbits the sun and has a round shape. The crucial difference between a planet and a dwarf planet is that a dwarf planet is not large enough to clear the neighborhood of its orbit. Currently recognized dwarf planets are:<ref>http://www.answers.com/topic/dwarf-planet</ref> − *[[Pluto]] − *[[Eris]] − *[[Ceres]] − − − [[Asteroids]] are irregularly shaped chunks of rocks in the solar system. They exist mostly in 2 places: − − *The [[asteroid belt]], which is between the orbits of [[Mars]] and [[Jupiter]] − *The [[Kuiper belt]], which shares its orbit with [[Pluto]] − − − [[Comets]] are chunks of dust and ice. Some are in an [[ellipse|elliptical]] orbit around the sun, meaning that they will return someday. Some are in a [[hyperbola|hyperbolic]] orbit around the sun, meaning that they will only come into the solar system once and will never return. − − − − − [[Category:Astronomy]]
