Jupiter's moons in February 2028

Io · Europa · Ganymede · Callisto

Jupiter's four big moons put on a show every night: they slip behind the planet and into its shadow, cross its face, and drag their shadows across the cloud tops. Any telescope shows it. Pick your place: the calendar and the nights keep only what your sky shows.

Where the moons are

Jupiter · February 2028

Jupiter's equator horizontal, east to the left as in binoculars. Drag through the month, or tap any event below to jump there; full screen (⤢) steps through a single night a minute at a time. Moons behind the planet fade, a moon in Jupiter's shadow is an empty ring, and a shadow on the disc is placed from the listed times. Positions ±0.1 Jupiter radii — for the picture; the times come from JPL.

Reading the list

Times are for the moment the moon's centre crosses the edge of Jupiter or of its shadow, the convention of published tables; the moon's own disc takes a few minutes to cross. 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 are from JPL DE431 and the jup365 satellite ephemeris, Jupiter as an oblate spheroid with its shadow cone. Mutual-event brightness drops assume uniform discs and are estimates. Events are geocentric — the same instant everywhere on Earth to well under a second.
