So as we go around the Sun, we
see the rings with different tilts
Telescope picture of
A large moon can be torn apart
by the “tidal” forces of the planet:
The gravity near the planet is
larger than the gravity on the far side
of the moon, away from the planet
When this tidal force is greater
than the self-gravity of the moon,
the moon disintegrates
Snowflakes to Boulders
How do we know?
Probably debris from moons,
not solar wind excite Saturn’s aurorae
probably the result of a really big collision
Has a big storm,
Similar to Jupiter’s
Big Red Spot
Retrograde, inclined orbit
