Jupiter's moons in February 2027

Io · Europa · Ganymede · Callisto · 5 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.

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.
