When does Venus reach its greatest apparent separation from the Sun for optimal evening sky viewing?
Answer
Maximum elongation
The period when Venus is most spectacularly visible in the evening sky corresponds to when it achieves maximum elongation. Elongation is the measurement of the angular distance between Venus and the Sun as viewed from Earth. Reaching maximum elongation signifies that the planet has achieved its greatest apparent separation from the Sun in the sky, maximizing the time it remains visible after sunset and making it the easiest object for observers to spot.
