帮我翻译一下,拜托了!
When man began to search the skies,he saw a lot of things.In theuniverse,the earth seemed to be just a small bit of dust.It is only a small planet,and travels around the sun.The sun,together with its planets,travels,travels in the Millky Way,our galaxy.The Millky Way has about thirty billion stars like our sun,and is one of about a hundred million galaxies in the universe.
Because the space is so great,it is difficult to work out how far away a star is.Instead of kilometers,we have light-years.A light year means the distance light travels in one year.Our nearest neighbor galaxy is more than 900000 light-years away from the earth.
很急!!!!!!!!!
在人类开始探究天空时,人们看到了许多的东西.在这个宇宙中,地球小若尘埃,它只是一颗小行星,不停歇得绕日运动.太阳,和以他为中心的行星们,在宇宙的银河——我们的银河系中运行.银河系里约有300亿颗像太阳的恒星,而在整个宇宙中,又有近1亿个银河系这样的星系.
宇宙广袤深远,想要度量恒星之间的距离是不容易的.现在人类不是用千米,而使用光年这一天文学上的距离单位来计量星星之间的距离.光年是指光在一年内在真空中走过的路程.与我们所在银河系最邻近的另一银河系距地球有90多万光年远.
光年的定义来源于《现代汉语词典》.
