回答1:

天蝎座是天空中十二个黄道星座中面积最大的星座.
如果你想了解更多有关星座星星的相关知识,个人建议你可以去看一下天文论坛,牧夫天文论坛、天之文天文论坛都是比较OK的网站。

回答2:

十二星座都是指的恒星,都离我们非常非常遥远,星星的数目也是数不清的。
十二星座是人为划分的天空区域,不是指某个天体

回答3:

十二星座并不是指某个系统,星座是由人类肉眼可见的发光星体加上人的想象力描述出来的。即使是同一个星座里面的发光体也不一定是属于同一个星系系统。有些发光体甚至就是一个星系。比如说,在你面前的一根蜡烛 跟距离30米外的手电筒 你观察到的亮度是一样的

太阳系目前所知的八大行星,可分为两大类。一类是与地球类似的,有着坚硬石质外壳的“类地行星”,类地行星的化学构成,是以硅酸盐为主,它们密度大,体系小,有固体的表面。
  太阳系当中的类地行星,从里向外分别包括水星、金星、地球和火星。而因为火星轨道外侧是一条小行星带,因此类地行星又叫“带内行星”。类地行星的卫星非常少,水星和金星原本更是没有卫星。
  另一类是“类木行星”,也叫“巨行星”或“带外行星”。类木行星的构成,以氢和氦为主,体积大,密度小,表面为气体。它们的特点是体积都非常大,而且没有固态的外壳。太阳系内的类木行星,包括行星之王木星,以及土星、天王星和海王星。类木行星的另一特点是它们都有环,其中尤以土星的环最为显着。类木行星的卫星众多。
  此外,太阳系内还存在着一类“矮行星”,该类行星体积较小,基本上都位于海王星的轨道之外,且不能依靠自身质量和引力,清除其轨道上的其他天体。这类行星包括冥王星及其卫星卡戎星,还有齐娜星和谷神星等。在火星和木星的轨道间,横亘着一条小行星带,带内分布着数不清的小行星。小行星和行星都诞生自太阳星云,但它们的体积过于微小,在广阔的太阳系内可说是微乎其微。
  除了上述按照结构特征和化学构成进行分类的方式,还有按照它们各自与太阳距离的远近,把天王星和海王星归类为远日行星的分法;以及根据体积和质量的大小,将木星和土星归为巨行星的分法。
  结束语:分类,即是把事物的性质、特点等作为区分的标准,将符合同一标准的事物聚类。但一直以来,对八大行星的分类,却未有个完全统一的标准,当下的教科书,多是综合运用了结构特征、体积大小和距离远近等依据进行划分,有时未免令人感到混乱,而这也是需要专家学者们进一步完善的问题。
