planet
/ˈplænət/
The word evokes a sense of vastness, isolation, and cosmic scale. While it primarily refers to an astronomical entity, the mental image is one of a self-contained world drifting in a vacuum. In metaphorical contexts, it suggests a total preoccupation or an all-encompassing focus, where a person's entire emotional or social existence revolves around a single point of gravity. Compared to 'world', which often refers to the human experience or a specific society, 'planet' emphasizes the physical, spherical nature of the body and its place within a larger stellar system.

Etymology
The word 'planet' comes from the Greek word 'planētēs', meaning 'wanderer'. Ancient Greek astronomers observed that certain celestial bodies moved across the sky differently than the stars, which appeared fixed in patterns. These 'wandering stars' were named 'planētēs'. The concept evolved through Roman and medieval astronomy, eventually solidifying into the modern definition with the understanding of the heliocentric solar system.
