Answer:

There is some sort of relationship of density to this classification. Mean density for gas planets is far less than that for terrestrial planets. The ratio is nearly 1 : 5..

Explanation:

Density Table ( courtesy: NASA Planetary Table):

Density (g/cc)

Mercury-5.427 Venus 5.243 Earth-5514 Mars 3.933

Jupiter-1.326 Saturn 0.687 Uranus-0.271 Neptune 1.638

The mean density for the terrestrial planets Mercury, Venus, Earth

and Mars is 5.038 gm/cc

The mean density for the gas planets Jupiter, Saturn, Uranus and

Neptune is 0.9805 gm/cc
