(ii)They are lying between the sun and the belt of asteroids.
(iii)These are solids like earth.
(iv)These are known terrestrial planets.
(iv)They are relatively smaller and their lower gravity does not hold the escaping gases.
Outer planets:
(i)The outer planets are Jupiter, Saturn, Uranus, Neptune and Pluto.
(ii)They lie away from the asteroid belt.
(iii)These are gaseous planets as they are made up of gases.
(iv)They are called Jovian planets.
(v)They are relatively larger in size. Their higher gravity holds up the gases.
