figure it out
Inner planets are also known as Terrestial planets which means they all have a rocky surface.
High density, small size.
They all do have gravity, an axis, and all revolve around the sun.
I do no know what the inner planets share but the outer planets except Pluto are gas giants. inner our "rocky" ^_^
The inner planets, also known as the terrestrial planets, share several key characteristics. They are primarily composed of rock and metal, giving them solid surfaces. Additionally, they have relatively high densities and smaller sizes compared to the outer planets. Inner planets also have fewer moons and no ring systems, and they exhibit significant geological activity, such as volcanism and tectonics.
As of now, there are no known planets that are exactly the same as Earth in terms of all its characteristics. However, there are planets known as "Earth-like" planets that share some similar characteristics such as being in the habitable zone of their star and having the potential for liquid water on their surface.
That they all inner planets
they al are outer planets.
all outer planets aremade of gashave a thick atmospherethey have ringsand they are huge
That refers to "planets" which don't orbit stars - technically they would therefore not be planets, though they may share many other characteristics of planets.
they al are outer planets.
Nothing, there not the same. They don't share characteristics.
