What is the maximum angular separation, in degrees, that Venus reaches from the Sun as viewed from Earth?
Answer
About 47 degrees
The timing and duration of Venus's visibility as the Morning or Evening Star are determined by its maximum angular separation from the Sun, as observed from Earth. This maximum angular distance is a fixed geometric property based on the relative sizes and distances of the orbits of Earth and Venus. The text specifies that this maximum separation, which defines the longest viewing windows in the twilight sky, reaches approximately 47 degrees. When Venus reaches this limit, it is at its greatest elongation, marking the peak time for observing it shortly after sunset or before sunrise.
