in addition to the earth how many planets can be seen with the unaided eye
In classical antiquity, the sacred Seven Luminaries or what we now call the Seven Classical Planets are the seven non-fixed objects visible in the sky with the naked-eye: the Moon, Mercury, Venus, the Sun, Mars, Jupiter, and Saturn. The word planet comes from the Greek word πλανήτης, planētēs "wanderer" (short for asteres planetai "wandering stars"), expressing the fact that these objects move across the celestial sphere relative to the fixed stars.
