there are none, if you're not counting Pluto as a planet.
Yes it is every other outer planet is made of gas but some believe that in the center of Jupiter lies a rocky core.
It is not small and rocky, it is a gas giant!
That would be Pluto, but Pluto is no longer considered a planet, only a planetoid.
The planet is Pluto
Venus is the only planet orbiting the sun with a thick, hot armosphere and a rocky surface.
Yes. The others are gas giants.
Saturn is not a terrestrial planet, so it is a gas planet.
Ours - Earth.
Saturn does not really have a surface. The only hard part of Saturn is its rocky core. The "surface" of Saturn is actually hydrogen and helium kept in a spherical shape by the planet's gravity.
Inner planets are made of rocky materials and metals, while the outer planets are made up of gases (Hydrogen and Helium) and are referred to as "Gas Giants". Pluto is the only outer planet that does not follow these characteristics. Pluto was deemed not a full-fledged planet recently.
Eris is an OUTER planet. The only inner planets are mercury, venus, earth and mars. An outer planet is not related to the size of the planet but rather the distance from the sun.
The terms "outer planet" and "inner planet" are only used for planets. Pluto is not a planet, and it orbits beyond the outer planets.
