Gas giant. Age ranges from 2-10 billion years. Diameter is 50,000 to 140,000 km. Typically located in the Cold Zone of a planetary system. Surface radiates some heat and is tenuous and comprised of gaseous hydrogen and hydrogen compounds, atmospheric zones vary in temperature, pressure and composition. May contain hydrocarbon-based life forms.[1]
