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.
