sun, moon and the earth

The Moon travels around the Earth. It takes 28 days to go around this orbit
Earth moves around the Sun, it takes 365 days (one year) to go all the way around. As the Earth moves around the sun it is spinning. It takes 24 hours (one Day) to spin around on its axis ( the axis is just an imaginary line that goes through the middle of the Earth from the North pole to the South pole.)The part of the Earth that is facing the Sun is lit up, it is daytime here, but the other half of the world is facing away from the Sun so it is in darkness. As the Earth turns on its axis different parts turn to face the Sun and this is why we get day and night. If you were standing on the Earth (and you probably are!) you would see a very different picture. From here it looks as if the Sun is moving accross the sky, rising in the East and 12 hours later setting in the West. The Moon appears to move across the night sky just as the Sun does during the day. But as well as moving across the sky the moon appears to change its shape from one night to the next. It seems to start as a thin crescent then get fatter and fatter until, after a couple of weeks, it is a full moon. Then it gets thinner and thinner until it becomes a crescent shape and then turn to a new moon
