Earth is the planet we all live on . Although we assume that our Earth is very big , it is actually very small compared to the other planets in the Solar System . The average diameter of the Earth is 12735km .

The Earth is the third planet from the Sun . It takes 24 hours to make one rotation abut its own axis and 365¼ days to make one orbit around the Sun .

Earth is very special in the sense that it is a planet that has air and water . The layer of the atmosphere filters some sunlight to enable animals and plants to live safely on it . The distance of Earth from the Sun is neither too far nor too near . The Earth is also beautiful because it has four seasons .

The Moon is the natural satellite of the Earth , If the Moon is at the position exactly between the Earth and the Sun, the phenomenon called the eclipse of the Sun will occur . The Sun is blocked by the Moon and the Earth becomes totally dark . Have you ever seen an eclipse of the Sun ?
