1. What is the primary gas in the Jovian atmospheres? The primary gas is Hydrogen


2. What is the primary gas in Mars and Venus? The primary gas is Carbon dioxide
3. If you had to visit one planet, which would it be? Why? Give me a solid paragraph. (consider many factors such as location, temperature, atmosphere composition, and anything else you you feel is important) If I was to visit a planet I would say Pluto because it is an unexplored planet that pleople have not been to. I know that it's really cold, and I like cold places. Pluto might contain diffrent gases that we don't know of, and I would want to discover them myself.
