what are three characteristics of the outer planets
The outer planets consist of Jupiter, Saturn, Uranus, and Neptune. These are all gas giants and, to our knowledge, none of them have a solid surface. They all also are signifâ¦icantly larger than Earth.
Eventually, some of these molecules began to accumulate together, forming small discs and then eventually spheres. The outer planets all formed from frozen gases, and as a result they are made up primarily of elements such as helium and hydrogen. They are also considerably larger than the terrestrial planets, and their enormous size results in massive gravitational forces.
