Yesterday, I went to the Museum of Natural History. I saw very many things in there. There was a movie about 'The Earth's Birth', dinosaur bones, and there was my favorite, 'Universe'.    I could see 9planets like Sun,  the 8 planets; Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. But the explanation under Pluto's picture said,  'Pluto is too small to call it a planet in our solar system. I thought   'Oh, I think astronomers are doing many things about the universe.'   When I go there one more time, I will see exhibits more carefully and know more about them. It was very good experience.

Great writing, remember there are only 8 planets now :)
