INNER PLANET Meaning and
Definition
-
Inner planets refer to a group of celestial bodies in our solar system that are positioned closer to the Sun than the outer planets. Often referred to as terrestrial planets, these four inner planets include Mercury, Venus, Earth, and Mars. They are characterized by their solid, rocky surfaces which differentiate them from the gas giants that make up the outer planets.
Mercury, the planet closest to the Sun, is the smallest and fastest of the inner planets. Being nearest to the Sun, it experiences extreme temperatures and has a thin atmosphere. Venus, the second inner planet, is often called Earth's twin due to its similar size and composition. However, its thick atmosphere makes Venus the hottest planet in our solar system.
Earth, the third inner planet, is our home and the only planet known to support life. It has a diverse range of ecosystems and an atmosphere that provides oxygen and protects us from harmful solar radiation. Mars, the last inner planet, has a thin atmosphere and is often referred to as the "red planet" due to its reddish appearance caused by iron oxide on its surface. Scientists have found evidence of water existed in the past, fueling the hope for the possibility of life.
Overall, the inner planets are distinct from the outer planets due to their smaller size, solid surfaces, and their relatively closer proximity to the Sun.

Etymology of INNER PLANET
The word "inner planet" is a combination of two separate etymologies.
Firstly, the word "planet" derives from the Latin word "planeta" meaning "wandering star". This term was used in ancient astronomy to describe the celestial bodies that move across the night sky and were distinct from the fixed stars. The Latin word itself has its origins in the Greek word "planetes", which has a similar meaning.
Secondly, the word "inner" comes from the Old English word "innemest" which means "most inward, nearest the center". It is a combination of the word "in" meaning "inside" and "-mest" which is a superlative suffix indicating the highest degree of something.
When these two terms are combined, the phrase "inner planet" refers to the celestial bodies in our solar system that are located closest to the sun, namely Mercury and Venus.
