What a Jupiter year means
Jupiter takes nearly 12 Earth years to go round the Sun, so it moves into a new zodiac constellation roughly once a year as seen from Earth, a pattern ancient astronomers tracked closely.

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.
