The visibility of Venus in the night sky is not solely dependent on its position between the Sun and the Earth. While Venus is an inferior planet (meaning it orbits closer to the Sun than the Earth), it can still be observed during certain parts of its orbit.
Venus goes through phases similar to the Moon because it orbits the Sun, and from Earth, we see different portions of its illuminated side. When Venus is on the side of its orbit closer to the Sun (inferior conjunction), it appears to be lost in the Sun's glare and is typically not visible. During this time, Venus is not visible at night since it is too close to the Sun in the sky.
However, as Venus moves away from the Sun in its orbit, it reaches its greatest elongation, which is the point where it is farthest from the Sun as seen from Earth. At this time, Venus appears as the "Evening Star" when it is visible after sunset in the western sky. Similarly, there is another point in its orbit where Venus is visible before sunrise in the eastern sky, known as the "Morning Star."
Therefore, the visibility of Venus depends on its position in its orbit and its angular separation from the Sun as seen from Earth, rather than its position between the Sun and the Earth. Even if Venus is orbiting between the Sun and the Earth, it can still be observed during the times when it is sufficiently separated from the Sun's glare and visible in the pre-dawn or post-sunset sky.
