Gasey Planets . =]

(1) Hydrogen Is The Number One Gas In The Jovian Planets.
(2) Carbn Dioxide Is The Most Abundant Gas In Mars And Venus.
(3) Out Of All The Planets I Would Like To Go To Neptune Because It Has A CLose Atmospheric Composition To Earth. It Also Has A Good Distance From The Sun. I Also Like The Size, Color, And STucture Of The Planet.
