Here's why:
* Inner Planets (Mercury & Venus): These planets orbit closer to the Sun than Earth. They are only visible near sunrise or sunset because they are lost in the Sun's glare when they are in the night sky.
* Outer Planets (Mars, Jupiter, Saturn, Uranus, Neptune): These planets can be visible throughout the night, sometimes even at midnight. However, their visibility depends on their position in their orbit. Sometimes they are in a position where they rise and set relatively close to the Sun, making them visible only for a short time after sunset or before sunrise. Other times, they are in a position where they rise and set far from the Sun, making them visible for longer periods throughout the night.
In summary:
* Inner planets are never visible at midnight.
* Outer planets can be visible at midnight, but their visibility depends on their orbital position.
It's important to remember that the specific visibility of planets varies depending on factors like time of year, location on Earth, and the current position of the planets in their orbits.
