Venus doesn't "light" in the way we think of light. It doesn't have any internal source of light like the Sun does.

Venus appears bright in the night sky because it reflects sunlight.

Here's a breakdown:

* Venus is a planet: Like Earth, it orbits the Sun.

* Sunlight: The Sun emits light and heat.

* Reflection: Venus's thick atmosphere, mostly composed of carbon dioxide, reflects a significant amount of sunlight back into space. This is what makes it appear so bright to us.

So, while Venus doesn't produce its own light, it does reflect sunlight, which is what we see as its "light".
