Answer:The four outer planets in our solar system, namely Jupiter, Saturn, Uranus, and Neptune, all exhibit faster rotation on their axes compared to Earth's period of rotation. This phenomenon is known as a shorter "day" on these planets due to their rapid spinning. For example, Jupiter completes a full rotation in about 9.9 hours, Saturn in about 10.7 hours, Uranus in about 17.2 hours, and Neptune in about 16.1 hours. This swift rotation contributes to the unique characteristics and dynamic atmospheres of these gas giants, impacting their weather patterns, magnetic fields, and overall planetary dynamics. Studying the rotation rates of these outer planets provides valuable insights into the broader understanding of planetary formation and evolution processes within our solar system.
