This story caught my attention. How do they just decide that its not a planet. If its not a planet then what is it? Science makes me nuts. How confusing it that for school children. They are changing the rules all the sudden. My science teacher in 5th grade told us of a little ryme to remember the planets. "My Very Eager Mother Just Served Us Nine Pizzas". Mars, Venus, Earth, Mercury, Jupitar, Saturn, Uranis, Neptune, and Pluto Now theres no Pizza!!!!
