At V band, the emission from airglow is V = 22 per square arc-second at a high-altitude observatory on a moonless night; in excellent seeing conditions, the image of a star will be about 0.7 arc-second across with an area of 0.4 square arc-second, and so the emission from airglow over the area of the image corresponds to about V = 23.
Zodiacal light spans the entire sky and contributes [7] to the natural light of a clear and moonless night sky. A related phenomenon is gegenschein (or counterglow ), sunlight backscattered from the interplanetary dust, which appears directly opposite to the Sun as a faint but slightly brighter oval glow.
The reason for this is that when Venus is closest to Earth, it is between the Earth and the Sun, so only its night side is seen. Even when Venus is brightest in the Earth's sky, humans see only a narrow crescent. For a Mercurian observer, on the other hand, Venus is closest when it is in opposition to the Sun
The Moon and Venus in the evening sky on three consecutive days. The centre image shows an appulse between the two objects. The centre image shows an appulse between the two objects. Appulse is the least apparent distance between one celestial object and another, as seen from a third body during a given period. [ 1 ]

Similarly, Joel Kowsky, the astronomer of NASA recorded the lunar occultation of Venus the same day from Washington, D.C. The lunar occultation of Venus on this date was the second lunar occultation of the Venus in the same year.
