Understanding Venus' Visibility
Venus, often referred to as the "Evening Star" or "Morning Star," is one of the brightest objects in the night sky. Its visibility throughout the year can be attributed to its position relative to the Earth and the Sun.
Why Venus is Visible at Dawn or Dusk
- Orbit and Position: Venus orbits the Sun at a distance closer than Earth. This means that it is often situated between the Earth and the Sun, making it visible during certain times of the day.
- Phases of Venus: Similar to the Moon, Venus goes through phases. During its cycle, it can be seen just before sunrise (dawn) or just after sunset (dusk), depending on its position in its orbit.
- Brightness: Venus reflects sunlight effectively, making it exceptionally bright, which contributes to its visibility at these times.
Comparison with Other Times
- Midnight: At midnight, Venus is usually on the opposite side of the Sun, making it difficult to observe.
- Noon: During midday, the Sun's brightness overshadows Venus, rendering it invisible to the naked eye.
- Throughout the Day: Although Venus can occasionally be seen during the day, it is not consistently visible due to the Sun's glare.
Conclusion
In summary, Venus can be observed most of the year primarily at dawn or dusk, making option 'C' the correct choice. Its unique position in the solar system allows it to shine brightly during these times, captivating skywatchers around the globe.
