Here's why:
* Venus is the brightest planet in our solar system. Its thick atmosphere reflects sunlight very effectively, making it appear exceptionally bright.
* Venus orbits the sun faster than Earth. This means it can appear in the sky both before sunrise (as the morning star) and after sunset (as the evening star).
It's important to note that while Venus is the most common "morning star" and "evening star," other planets like Mercury and Mars can also appear as such, depending on their position in their orbit.
