The stars we see at night are the suns in other galaxies.the solar systemstar 恒星 planets 行星Where do we live in the space?金星是美和爱的女神,之所以会如此命名,也许是对古代人来说,它是已知行星中最亮的一颗。因为它在夜空中看起来是血红色的,所以在西方,以罗马神

5、话中的战神玛尔斯(或希腊神话对应的阿瑞斯)命名它。因为它离太阳最远,因此也非常寒冷,这和罗马神话中的冥王普鲁托所住的地方很相似,因此称为“Pluto”。在2006年8月24日于布拉格举行的第26届国际天文联会中通过的第5号决议中,冥王星被划为矮行星,并命名为小行星134340号,从太阳系大行星行列中被除名。所以太阳系暂时只有八颗大行星。 Mercury 水星Earth 地球Mars 火星Saturn 土星Neptune 海王星Venus 金星Jupiter 木星Uranus 天王星Pluto 冥王星在古罗马神话中水星是商业、旅行和偷窃之神,即古希腊神话中的赫耳墨斯,为众神传信的神,或许由于水星

6、在空中移动得快,才使它得到这个名字。在西方称它为朱庇特,是罗马神话中的众神之王,相当于希腊神话中的宙斯。土星是太阳系中仅次于木星的第二大行星。土星的英文名字Saturn是以罗马神的农神萨杜恩命名的。土星也是英语中“星期六”(Saturday)的词根。以直径计算,天王星是太阳系第三大行星;但若以质量计算,则比海王星轻而排行第四。天王星的命名,是取自希腊神话的天神乌拉诺斯。海王星的名字是罗马神话中的海神涅普顿(Neptune)。Do you think there are plants or animals on other planets?In order to find the answer,
