A long time ago people thought that sun went round the earth...
A long time ago people thought that the sun went round the earth.In some
countries people even said that the sun was a god(神).They thought the god
drove across the sky each day on a golden horse.Now we know the earth goes
round the sun.It takes the earth a year to go all 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 journey 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 ever go to
the sun.It is far too hot for people to live anywhere near it.The sun is three
hundred thousand times heavier than the earth and more than million times larger.
