天文常识大全英语

1.有关天文学的知识,用英语翻译

太阳和太阳系的年龄

地壳中最古老岩石的年龄经放射衰变方法鉴定为略小于40亿岁。用同样方法测定的月球岩石样品年龄大致从41亿岁直到最古老月岩样品的45亿岁。有些陨星样品也超过了40亿岁。综合所有证据得出太阳系大约是46亿岁。由于银河系已经150亿岁左右，所以太阳及其行星的年龄只及银河系的三分之一。虽然没有测量太阳年龄的直接方法，但它作为赫罗图主序星上一颗橙黄色恒星的总体外貌，却正好是对一颗具有太阳质量、年龄约46亿岁、度过了它的一半主序生涯的恒星所应该期望的（英语翻译）Theageofthesunandsolarsystem

3.用天文术语名称等来起英文名

1.你可以按照星球的名字做名字：Star星星；Mercury水星；Venus金星；Earth地球；Mars火星（这个不错）；Jupitor木星；Saturn土星；Neptune天王星；Uranus海王星；Pluto冥王星

2.你可以按照天文方面牛人的名字：NicolausCopernicus;StephenHawking;GalileoGalilei;CarlSagan;JohannGottfriedGalle;JohannesKepler;MichaelE.Brown

7.高中生怎样学好天文知识

首先兴趣是最关键的，数学物理基础要非常好，再学好计算机、英语。至于星星看看就行，那属于启蒙基础，应该早就认识才对。不过很多天文学家都认不全天上的星星，不在少数。推荐你《天文学新概论》。已出了3版，此书讲述系统，较为专业，非常适合初学者全面掌握天文知识，一些大学选其为选修课教材。相信你看后不会失望。这本书不宜买到，我当年是从北京天文馆邮购的，你可去卓越亚马逊网上买到。

《天文爱好者》是本很棒的杂志。忠实的天文爱好者，永不放弃星空！
