ELI5: Why is venus only visible a few hours after sunset?
gpt
Venus's orbit lies between Earth's orbit and the Sun.

During the day you can't see Venus for the same reason you can't see any stars - the Sun is too bright.

During the night you can't see Venus for the same reason you can't see the Sun - it's "behind" the Earth.

The only time when Venus is visible is either right after sundown or right before sunrise, since at that point the Sun isn't bright enough to block out Venus, but Venus isn't completely hidden behind the Earth.
