One year on Uranus lasts about 84 Earth years, which reflects the difference in orbital scales across our solar system. This length results from Uranus’s distance from the Sun at about 19.2 astronomical units and its rotational period of roughly 17.24 hours.
To understand Uranus’s long year, it helps to compare it with geological timescales. Movement of tectonic plates on Earth can take millions to billions of years to reshape regions. Since a Uranian year is only 84 Earth years, it is far too short to match the duration of an Earth geological era. This removes the idea that such long geological phases could unfold inside a single Uranian year.
Relativistic time invites examination of the nature of time itself. Although physics often treats time as a dimension with uniform flow, Einstein’s theory of general relativity shows that gravity alters spacetime. This effect, known as gravitational time dilation, causes clocks to run at different rates depending on gravitational strength. Clocks on Earth run about 0.014 seconds slower per year compared with clocks in orbit due to the difference in gravitational potential combined with corrections from orbital speed.
