Solar System (太阳系)We are in the solar system is the star system. It is based on the sun as the center, and all of the gravity constraint by solar collection of objects: 8 planets Pluto has fired, at least 165 of the known satellites, and hundreds of millions of small bodies in the solar system. These small bodies, including the asteroid kuiper belt objects, the cometary and interstellar dust. In general, the solar system including the sun, 4 star field like the earth of the inner planets, by a lot of small rock composed of the asteroid belt, 4 full gas giant planets, full of freezing the small rock, is called the kuiper belt objects of the second small area. In the kuiper belt, there is a discrete disk, the sun zodiac ring and still belongs to the assumption of the oort cloud.(太阳系就是我们现在所在的恒星系统。它是以太阳为中心,和所有受到太阳引力约束的天体的集合体:8颗行星冥王星已被开除、至少165颗已知的卫星,和数以亿计的太阳系小天体。这些小天体包括小行星、柯伊伯带的天体、彗星和星际尘埃。广义上,太阳系的领域包括太阳、4颗像地球的内行星、由许多小岩石组成的小行星带、4颗充满气体的巨大外行星、充满冰冻小岩石、被称为柯伊伯带的第二个小天体区。在柯伊伯带之外还有黄道离散盘面、太阳圈和依然属于假设的奥尔特云。)
