Venus doesn't appear in the night sky. It's actually a morning or evening star, meaning it's visible before sunrise or after sunset.

Here's why:

* Venus orbits closer to the Sun than Earth. This means it's always relatively close to the Sun in the sky.

* Venus reflects sunlight. It's visible because sunlight reflects off its thick atmosphere.

* Venus's position relative to the Sun changes over time. This is why sometimes it's visible in the morning sky and other times in the evening sky.

To know the exact time Venus appears, you'll need to check an astronomy website or app that provides information on celestial objects' visibility for your location.
