Saturn's moons in September 2028

Mimas · Enceladus · Tethys · Dione · Rhea · Titan · Iapetus — eclipses, occultations, transits, shadows

Saturn's moons hide behind the globe, cross its face and fall into its shadow only in the years around a ring-plane crossing, when their orbits turn edge-on to us — as they are now, after the 2025 equinox. Titan is easy in any telescope; Rhea, Dione and Tethys need a little more aperture. Times are for the whole Earth; pick a location and the list keeps only what your sky shows.

Where the moons are

Saturn's equator horizontal, east to the left as in binoculars. Drag through the month, or tap any line in the list below to jump there. Moons behind the planet fade. Positions are JPL's, sampled hourly; the rings are not drawn.

Events

Reading the list

Each disappears / reappears line is the moment the moon's disc is fully in or first out; the "takes N min" is how long the disc takes to cross the edge. Halves that happen behind Saturn or inside its shadow are left out, since nobody can see them. Positions are from JPL DE431 and the sat441 satellite ephemeris, Saturn as an oblate spheroid with its shadow cone; the rings are not modelled, so a moon 'behind Saturn' means behind the globe; mutual-event magnitude drops assume uniform discs and are estimates. Events are geocentric — the same instant everywhere on Earth to well under a second.
