The planet known for having a tilt that causes extreme seasons is Uranus. This unique axial tilt is approximately 98 degrees, meaning that it essentially rolls around the Sun on its side. As a result, Uranus experiences extreme variations in sunlight and temperature as it orbits the Sun, with each pole receiving 42 years of continuous sunlight followed by 42 years of darkness. These unusual seasonal changes make Uranus one of the most intriguing planets in our solar system, leading to fascinating atmospheric phenomena and weather patterns, including intense wind and temperature fluctuations.
