Cool Saturn Pictures

Casinni at Saturnian Equinox
Whereas the earth is tilted at 23 1/2 degrees, Saturn's obliquity as astronomer call it is very close, almost 27 degrees. So, Saturn has seasons as it travels around the sun. Since its year is about 30 earth years, Saturn has much longer seasons. Twice during the long Saturnian year the planet goes through an equinox, where the sun shines directly on the planet's equator and one of those equinoxes is happening now.

Nifty stuff.
