If an observer looks towards the western horizon just after sunset and sees Venus, what historical title is it earning at that time?
Answer
Evening Star
Venus is renowned for its cyclical visibility, earning dual historical monikers based on when it appears relative to the Sun's transit. When Venus is visible in the early morning sky before sunrise, it is referred to as the Morning Star, requiring observers to look toward the eastern horizon as dawn approaches. Conversely, when the planet is visible in the western sky just after the Sun has set, it is fulfilling the role of the Evening Star. This role reversal is entirely dictated by Venus's orbital mechanics as it swings around the Sun relative to Earth's position.
