Question

A long time ago people thought the sun went around the earth. 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 one and a half thousand kilometers a minute on its way round—the sun.

The sun is really a star. It's much bigger than the earth and it is very hot. Some people have been to the moon，but we know no one can go to the sun.
