Jupiter's moons in July 2028

Io · Europa · Ganymede · Callisto

Jupiter's four big moons put on a show every night. They pass behind it, into its shadow and across its face, and their shadows cross its clouds. Any telescope shows it. Pick your place to see only what's visible from there.

Where the moons are

Jupiter · July 2028

Jupiter's equator horizontal, east to the left as in binoculars. Drag through the month or tap an event to jump to it. Full screen (⤢) steps through one night minute by minute. A faded moon is behind the planet; an empty ring is a moon in its shadow. Positions ±0.1 Jupiter radii, for the picture; the times come from JPL.

Reading the list

Times are when the moon's centre crosses the edge of Jupiter or its shadow, as in published tables. The whole disc takes a few minutes. A start or end marked unseen happens behind Jupiter or inside its shadow. “Only what I can see” keeps events with Jupiter more than 10° up in a dark sky. Positions: JPL DE431 and jup365, with Jupiter as a flattened globe. Mutual-event brightness drops are estimates. Each event happens at the same instant everywhere on Earth.
