There are some people who did not expect that Saturn is the 2nd biggest planet probably because it is the least dense out of all the planets that are part of the solar system. This planet is made of a lot of gases so it will not have any other components that will make it heavy. In terms of size, this is 2nd next to Jupiter.
The size of Jupiter is at 142,984 kilometers. Saturn, on the other hand, has a size of 120,536. When the planets are being measured, they usually do it through the equator. For those who are not aware, Saturn is the sixth planet from the sun and is considered to be an outer planet.
