Uranus rotates almost on its side.

Uranus rotates with its axis tilted about 98 degrees relative to the upright direction of its orbit. Its poles therefore lie nearly in its orbital plane. This sideways arrangement creates seasons unlike those on Earth, with long intervals of sunlight or darkness near the poles.
