Explanation: 

Detailed explanation-1: -A planet’s density is related to its composition. The four inner terrestrial planets are dense compared to the four outer planets. The inner planets are made up mainly of dense, solid rock. The outer planets are composed primarily of gas, so their overall density is lower.

Detailed explanation-2: -Complete answer: Inner planets are those which are small in size such as Mercury, Venus, Earth and Mars. Earth is the largest inner planet and Mercury is considered to be the smallest inner planet. On the other hand, outer planets are those which are huge in size, for example – Jupiter, Saturn, Uranus and Neptune.
