∙ 10y agoThe inner planets are smaller, rocky, and receive more solar heat. They have solid surfaces, as opposed to the dense atmospheres around the gas giants.
The four inner planets have few moons whereas the outer planets have many.
Mercury and Venus have none. Earth has one and Mars has two.

∙ 12y agoAll are mostly rock rich in iron and silicon.
All had expensive scientific missions to study them (think earth is an exception? Do you know how many people died so we could understand our home?!)
All are far smaller than the gas giants
All spin in the same direction (venus Very! slooowly)
