Is the moon a planet?This question is fundamental if students are to show that they understand the nature of astronomy.Some scientists think that the earth gave birth to the moon because the moon circles our planet.Others believe that the moon existed before the earth was formed.They think that earlier in time it travelled through space as a small planet which was caught by the earth’s gravity.As a result ,it goes around our planet.The evidence for this theory is that the atoms that make up the rocks on the moon seem to be different from those on earth.What is clear is that the moon is smaller than the earth and this prevents it from escaping form the earth.Although its origin may still be a puzzle ,the moon can never be anything more than a satellite of the earth.
求通順

解答：

月球是一個星球嗎?如果學生們要證明他們理解天文學的本質,這是個基本的問題.有些科學家認爲月亮是從地球分離出去的,因爲月亮圍繞著我們的星球轉動.另一些認爲月球早在地球形成之前就已經存在.他們認爲它曾經作爲一個小星球穿越宇宙,結果被地球的引力捕獲.因此它現在才繞著我們的星球轉動.這一理論的證據是,構成月球上的岩石的原子,似乎與地球上的不同.可以明確的是,月球比地球小,這使它無法逃離地球.雖然它的起源可能仍然是一個謎,但月亮將永遠是一顆屬於地球的衛星.
