Io keeps the same face toward Jupiter as it orbits the planet. For this reason, Jupiter appears to hang motionless in Io's sky. Just as the Earth's Moon does, Jupiter goes through phases as Io orbits it. Here's a gallery showing the view from a location in the northern hemisphere during the course of a single day. 3. A little over ten hours into Io's day and Jupiter is in its first quarter phase.
