Our wonderful solar system!

I've been wondering about our wonderful solar system! I’ve been wondering, I’ve notice if you look at your backyard and your house, don't you think it is kind of like space? I’ll explain. Imagine your house is the sun and there are 8 kids and one baby running around the house. Why I said 8 kids is because of course, there are 8 planets. Mercury, Venus, Earth, Mars, Jupiter, Saturn , Uranus, Neptune and last but not least the baby...Pluto. Why is this planet a baby? Some scientists do not believe that it is big enough to be a planet, so they refer to it as a dwarf or a baby.
