Planets look bright because they give off visible light of their own.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Statement**: The statement claims that planets look bright because they emit their own visible light. We need to evaluate if this is true or false.

2. **Identifying the Nature of Planets**: Planets are celestial bodies that orbit stars (like the Earth orbits the Sun). They do not produce their own light like stars do.

3. **Reflection of Light**: The brightness of planets is due to the light they reflect. The primary source of light for planets in our solar system is the Sun.

4. **How We See Planets**: When sunlight hits a planet, it reflects that light back into space. This reflected light travels to Earth, allowing us to see the planets.

5. **Conclusion**: Therefore, the statement is false. Planets do not emit their own light; they are visible because they reflect the light from the Sun.

**Final Answer**: The statement "Planets look bright because they give off visible light of their own" is false. Planets reflect the light from the Sun, which is why they appear bright to us.
