Saturn's axial tilt is similar to that of the earth. Why does Saturn experience different length of seasons compared to earth?
guajiro [1.7K]

Answer:

Because Saturn has a longer orbital period.

Explanation:

The length of seasons is not determined by axial tilt, but by orbital period. The seasons we define on Earth take a quarter of the orbital period (year) each. So, since our orbital period is of 12 months, each season takes 3 months. Saturn has an orbital period of about 29 years, so each season would take over 7 years.
