Jupiter's moons in June 2027

Io · Europa · Ganymede · Callisto · 2 mutual events

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. This is a mutual-event season: the moons' orbits are edge-on to the Sun, so they eclipse and hide each other. Pick your place to see only what's visible from there.

Where the moons are

Jupiter · June 2027

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.
