Planetary Comparison

One of the most important areas of astronomy is the field of Comparative Planetology. By studying planets and other large bodies in the solar system, we learn about the history and possible future of our own.
There are nine planets in our solar system namely Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. These nine planets are classified into two groups: Jovian and Terrestrial, except for Pluto which is an entirely different system. These planets were classified as Jovian and Terrestrial Because of the differences that these two types of planets have. Here is a chart of the differences between these two types of classification:
Comparison of the Terrestrial and Jovian Planets
