You can change your choices at any time by visiting Your Privacy Controls. Gas giants can, theoretically, be divided into five distinct classes according to their modeled physical atmospheric properties, and hence their appearance: ammonia clouds (I), water clouds (II), cloudless (III), alkali-metal clouds (IV), and silicate clouds (V). In recent years, astronomers have designed a new class called the “dwarf planets.”. Its mass is almost 85±4 times the gas giant, the study said.

Neptune is the fourth largest planet in terms of diameter, making it the smallest in physical size of the gas giants. Jupiter is a gas giant, being majorly made of hydrogen while a quarter of its mass is helium. It is, arguably, something of a misnomer because throughout most of the volume of all giant planets, the pressure is so high that matter is not in gaseous form. Jupiter Narrowly missing the title of the biggest gas giant as it has yet to be confirmed if it is indeed a planet and not a brown dwarf, CT Cha b is pipped to the post by HAT-P-32b.
