interior planet Meaning

Definition of “Interior Planet”

An interior planet refers to any planet that orbits the Sun inside the Earth’s orbit. In our solar system, the interior planets are Mercury and Venus. These planets are closer to the Sun compared to the Earth and thus have shorter orbital paths.

Etymology

The term interior comes from the Latin word interior, which is the comparative form of intrors, meaning “within” or “inside.” The term planet originates from the Greek word planētēs, meaning “wanderer,” which reflects the ancient observation of these celestial bodies moving across the sky relative to the fixed stars.
