What a Uranus year means
Uranus has been known to science since 1781, and it has completed only about three orbits since. Its 98° tilt turns its 84-year year into a single, extreme cycle of seasons.

The farther out a world orbits, the longer its year, and not just because the path is longer: the Sun's pull is weaker out there, so the outer planets also move more slowly. In the interactive view, speed up time and watch the inner planets lap the outer ones.
