Jupiter's Great Red Spot is a long-lived anticyclonic storm in the planet's atmosphere.

Ganymede is the only moon known to generate its own magnetic field, likely because of a liquid iron core.

Jupiter rotates once in roughly 10 hours, and centrifugal effects push its equator outward.

Impacts on Jupiter's small moons loft dust into orbit, creating rings far dimmer than Saturn's mostly icy rings.
