Jupiter, the largest planet in our solar system, has played a crucial role in protecting Earth from comets. Its massive gravitational field acts as a shield, deflecting or capturing many comets and asteroids that might otherwise collide with Earth. This gravitational influence reduces the frequency of potentially catastrophic impacts on our planet. Reference:

1. **Wave Speeds**: The speed of different types of waves varies significantly. 2. **Gamma Waves**: These are electromagnetic waves that travel at the speed of light (approximately \( 3 \times 10^8 \) m/s). 3. **Radio Waves**: Another type of electromagnetic wave, also traveling at the speed of light. 4. **Visible Light Waves**: These are also electromagnetic waves traveling at the speed of light. 5. **Sound Waves**: Travel much slower compared to electromagnetic waves, with typical speeds in air around 343 m/s. 6. **Conclusion**: Among the given options, sound waves travel the slowest. **Reference**: - Wave Speed Comparisons: Differences in propagation speeds of sound and electromagnetic waves.

Kepler's discovery that planets move in elliptical paths around the sun is an example of a scientific law. A scientific law describes a relationship in nature that has been consistently observed to be true. Kepler's laws of planetary motion describe the predictable patterns of planetary orbits, which have been repeatedly confirmed through observation. Reference:
