Space & science
Even the Sun cannot keep one rotation schedule.
The Sun’s plasma rotates faster at the equator—about 25 Earth days—than near its poles, about 36 days.
The idea
One average can conceal important differences within the thing being measured.
An example
A useful visual model is two marked bands turning at different speeds. It illustrates why a solid-ball analogy fails for the Sun. The bands are a teaching analogy, not a description of separate physical shells.
Try it
When someone gives one number for a whole system, ask what varies inside that system.
More context
Its plasma rotates at different rates: about 25 Earth days at the equator and 36 near the poles. A single rotation period does not describe every latitude. Astronomy · approximate durations
