Answer:
Saturn is the distinct and large gaseous planet in the solar system that is comprised of a ring on its exterior. It is a planet which has the lowest density. Saturn has an atmosphere of very high thickness and the dominant gas present here is hydrogen and helium. The pressure and the depth in Saturn are directly proportional to one another.
As one goes deep inside the Saturn, the body will eventually shrink and get squashed due to the extreme pressure and also will get freeze due to the extremely low temperature.
