Here's why:
* Extreme Tilt: Uranus is tilted on its side, with its axis of rotation almost parallel to its orbital plane. This means its poles point almost directly at the Sun during its orbit.
* Long Seasons: Because of this extreme tilt, each pole experiences approximately 42 years of continuous sunlight followed by 42 years of continuous darkness. The equator experiences a more typical day-night cycle, but with days lasting around 17 hours.
This unique tilt makes Uranus a fascinating and unusual planet.
