Venus is the brightest planet in our solar system when seen from Earth. It is so bright that you can often see it with your naked eye, especially just after sunset or just before sunrise.

Venus is known as the “morning star” or “evening star” even though it is not a star at all. It looks very bright because:
- It is the closest planet to Earth (besides the Moon).
- It has thick clouds that reflect a lot of sunlight.
- It is covered with shiny, light-colored materials.

These clouds and surfaces bounce back sunlight, making Venus shine more than any other planet in the night sky.

Now let’s briefly look at the other planets in the options:
- **Jupiter** is the biggest planet and also bright, but not as much as Venus.
- **Mercury** is closer to the Sun but is much smaller and not as reflective.
- **Earth** is bright from space, but we are standing on it — we can’t see it shining in the sky.

So, although there are other bright planets, **Venus is the brightest** one we can see from Earth. It plays a big role in astronomy and is easy to spot even without any telescope.
