Now we know the earth goes round the sun. It takes the earth a year to go all the way round the sun . Today men even know how far it is for the earth to go round the sun. They tell us that the earth travels over a thousand miles a minute on its way round the sun.
The sun is really a star. It is much bigger than the earth and it is very hot. Some people have been to the moon, but we know that no one can go to the sun.
