The word "planet" in Greek is derived from the term πλανήτης (planētēs), which literally means "wanderer." This name was given because ancient Greek astronomers observed that certain celestial bodies moved across the sky relative to the fixed stars, hence they were called "wanderers".
The Greek verb πλανάσθαι (planasthai) means "to wander," from which the term πλανήτης originates. This reflects the movement of planets in contrast to the fixed position of stars.
Therefore, in Greek, "planet" means one that wanders or a wanderer in the sky.
