Root Explanation

**Planet** → It originates from the Greek word "planetes" (meaning wanderer). The term was used to describe celestial bodies that appeared to move across the sky in relation to the fixed stars. Thus, a planet is defined as a wandering celestial body.

Memory Tip

Imagine celestial bodies 'wandering' through the night sky — that's why we call them planets.
