Which “star” is actually a planet, often visible to the naked eye from Earth?

Venus

Venus, nicknamed the "Evening Star" or "Morning Star," is actually a planet, not a star. It is one of the brightest celestial objects in the night sky, just after the Sun and the Moon. Due to its proximity to Earth and its thick layer of reflective clouds, Venus shines with an intense brightness. Visible just before dawn or just after sunset, Venus has been observed by various cultures through the ages, often associated with beauty and love. The observation of Venus helped early astronomers to develop the heliocentric model of our solar system, marking a turning point in our understanding of the universe.
