SOLAR SYSTEM

Detailed explanation-1: -Comparative planetology is a scientific discipline in which researchers seek to understand the planets by comparing their similarities and examining their differences. Some planets have similarities because the materials of which they are made and the processes that have shaped them are similar.

Detailed explanation-2: -The comparison of greenhouse warming on Venus, Earth, and possibly Mars, is one example of a process that occurs at different levels on different worlds. The presence of life and liquid water is another example. They are present on Earth, but our two closest neighbors, Venus and Mars, currently lack either.

Detailed explanation-3: -Earth is a little more than 12, 000 kilometers in diameter. It differs from the other planets because it has liquid water on its surface, maintains life, and has active plate movement. It rotates on its axis every 24 hours (a day) and revolves around the Sun every 365 days (a year).

Detailed explanation-4: -Comparative planetology is the study of how planets work and evolve by comparing them and the processes that have influenced their development. This method allows us to learn about the origin and evolution of the entire solar system, instead of each planet as a discrete object in space.

Detailed explanation-5: -Knowing about the diversity of planetary processes is of paramount importance for understanding our planet Earth.
