That would be Pluto, but Pluto is no longer considered a planet, only a planetoid.
there are none, if you're not counting Pluto as a planet.
It is not small and rocky, it is a gas giant!
Yes it is every other outer planet is made of gas but some believe that in the center of Jupiter lies a rocky core.
Yes. The others are gas giants.
Not at all. Mars is the least dense of the rocky planets. Earth is the densest planet in the Solar System because of its large iron core. Mercury and Venus are only slightly less dense.All of the Gas giants are much less dense than the rocky planets. The least dense, Saturn, is actually less dense than water. (All of the gas giants have a much greater mass than the rocky planets but density is mass divided by volume)
It would be Venus, because that planet is the only one that has a solid crust.
The terms "outer planet" and "inner planet" are only used for planets. Pluto is not a planet, and it orbits beyond the outer planets.
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.
This isn't a rocky planet-Mars, Venus and Mercury are rocky planets. This planet can only really be described as a watery planet. We aren't really given the choice of which planet we live on, this is the only one so far that can support 'advanced' life.
The densest planet in the Solar System is Earth.The other inner planets - Mercury, Venus, and Mars - are only a bit less dense; all of them are much more dense than the four giant outer planets.Mercury is nearest the Sun and is the second densest planet.
The planet is Pluto
That is the planet Saturn.
