Which planet has a tilted axis that results in extreme seasons?

The planet known for having a significantly tilted axis, which leads to extreme seasons, is Uranus. Its axial tilt is about 98 degrees, meaning it essentially rotates on its side in relation to its orbit around the Sun. This unique orientation causes intense variations in sunlight received by different parts of the planet throughout its long orbit, which lasts about 84 Earth years. As a result, one pole can be in continuous sunlight for an extended period while the other experiences continuous darkness, creating extreme seasonal changes.

While Earth's axial tilt of approximately 23.5 degrees does result in seasonal changes, they are not as extreme as those on Uranus. Saturn and Jupiter also have axial tilts that result in seasons, but they are much less pronounced than those on Uranus. Jupiter, for example, has a tilt of only about 3 degrees, leading to mild seasonal changes. Saturn's tilt is more similar to Earth’s, but even then, the seasonal effects are not as stark as those experienced on Uranus.
