The word "PlanetMath" is a combination of two terms: "planet" and "math".
The term "planet" derives from the Ancient Greek word "planētēs" (πλανήτης), meaning "wanderer" or "wandering star". In ancient astronomy, the five visible planets (Mercury, Venus, Mars, Jupiter, and Saturn) were observed to move across the night sky differently from the fixed stars, hence the name "wanderers". Over time, the term "planet" expanded to include other celestial bodies that orbit a star, such as Earth.
The term "math" is a shortened form of "mathematics", which comes from the Ancient Greek word "mathēma" (μάθημα), denoting "knowledge", "learning", or "revelation".
