Planetary satellites

A planet and its satellites produce every kind of event at once: - A satellite goes dark when it enters the planet's shadow, or another satellite's. That is an eclipse, seen at the same instant by every observer. - A satellite disappears behind the planet's disc, or crosses in front of it. Those are an occultation and a transit, which depend on the observer's viewpoint. - A satellite's shadow falls on the planet. That is a shadow transit, an eclipse of a patch of cloud tops.

The topics here keep each planetary system together and label each event by its kind.

• Jupiter's satellites: the Galilean phenomena, the satellite theories and the mutual events.
• Saturn and the outer satellites: ring geometry, satellite phenomena, and mutual events at Saturn, Uranus and Pluto.
