To view Venus at 12 am when the dark side of the Earth is facing away from it, you would need to consider a few factors:
Time of Year: The position of Venus in the sky changes throughout the year due to its orbit around the Sun. Venus is an inferior planet, meaning it orbits closer to the Sun than Earth. As a result, Venus can appear in the evening sky after sunset or in the morning sky before sunrise, depending on its position relative to Earth.
Venus' Phase: Venus goes through phases just like the Moon, and its phase determines its visibility. When Venus is on the side of the Sun opposite to Earth (in its "full" phase), it is on the far side of its orbit and is generally not visible at midnight. However, when Venus is closer to Earth and on the same side of the Sun as us (in its "new" phase), it is visible in the pre-dawn or post-dusk sky.
Location and Local Time: Your viewing location on Earth also plays a role. The visibility of Venus can vary based on your latitude and longitude. Additionally, the local time at which Venus is visible will depend on your specific location and the time zone you are in.
Assuming you are in a location where Venus is visible at midnight, it would most likely be during the months when Venus is in its "new" phase and appears in the pre-dawn sky. In such cases, the planet can be seen in the eastern sky before sunrise, even though the night side of Earth is facing away from it.
