Hydrogen and helium atmosphere
Many moons
No land-atmosphere interface
Rocky surface

Answer 2

"There are a number of differences between the inner and outer planets aside from location. The inner planets are small, dense and composed mostly of rock, while the outer planets are composed mostly of gas, with no solid surfaces and only liquid cores. The inner planets also have few or no moons and no rings circling them, while the outer planets often have dozens of satellites and rings composed of particles of ice and rock."

Answer 9

Rocky Surface
The terrestrial planets all have rocky surfaces that feature mountains, plains, valleys and other formations. The temperatures of the inner planets are low enough that rock exists mostly as a solid at the surface. To different degrees, they also have meteor impact craters, although the dense atmospheres of Venus and Earth protect them from most meteors, and weathering and other factors wipe out all but the most recent craters. Mars has very low atmospheric pressure, and Mercury has almost none, so craters are more common on these planets.
