Planet, Class-J
Jupiter (ENT-50)
Saturn (TNG-101-102)
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]

Planet, Class-I
Gas Supergiant. Age ranged from 2-10 billion years. Diameter was 140,000 to 10 million km. Typically located in the Cold Zone of a planetary system. Surface radiated heat and was tenuous and comprised of gaseous hydrogen and hydrogen compounds, atmospheric zones varied in temperature, pressure and composition, and water vapor may have been present. No known native life forms.[1]

Class-D Planet (VOY-109)
In the Delta Quadrant, a massive Class-D planet was circled by many rings of Class-M asteroids, where the 247th element may have been discovered by the U.S.S. Voyager NCC-74656 crew in 2371. Over 200,000 Vhnori corpses rest as the “Next Emanation” among the asteroids.[1]

Asteroid/Moon. Age ranged from 2-10 billion years. Diameter was 100 to 1000 km. Typically located in the Hot Zone, Ecosphere or Cold Zone of a planetary system, primarily in orbit of larger planets or in asteroid belts. Surface was barren and cratered, atmosphere was nonexistent or extremely tenuous. No native life forms.[1]
