Which planet is unique in our Solar System for having its axis tilted almost 90 degrees, giving it the appearance of rolling?

Uranus has an axis that is tilted nearly 90 degrees, so that it almost runs parallel with the plane of rotation of the planets around the sun, instead of perpendicular like the rest of the planets. Uranus was discovered in 1781 by astronomer William Herschel, and was the first planet discovered with a telescope.
