Yes, given the correct circumstances, one may see many planets in our solar system with the unaided eye.
Venus, Mars, Jupiter, and Saturn are recognizable as "stars" that appear to move across the
sky over time and are frequently seen. People have been observing the skies for ever. Because early civilizations
documented their findings in writing and artistic forms, we know that they kept tabs on
the motions of the Sun, Moon, planets, and other stars. The night sky is still a fantastic resource, despite our
hectic modern lifestyles. Since the same stars and constellations emerge at the same time every
year, watching the gradual, continuous movement of the sky overhead from night to night and month to month is a powerful way to feel the cycle of the seasons.
