He’s right behind me, isn’t he? In this image snapped by NASAHubble, Jupiter’s largest moon, Ganymede, can be seen peeking out from behind the gas giant. Because of the angle of Ganymede’s orbit relative to Earth, this moon can often be spotted passing in front of Jupiter and ducking behind it. Not only is Ganymede Jupiter’s largest moon, it is also the largest moon in our solar system. Even so, Ganymede is dwarfed by Jupiter’s massive size. At its widest point, Ganymede is about 5,300 km in diameter—but Jupiter, at 143,000 km, is more than 25 times wider. Image description: The lower half of Jupiter takes up most of the space in this image. The planet is striped peach and beige, with round storms visible—including its iconic Great Red Spot. Ganymede, much smaller, peeks out from the bottom right of Jupiter, and is round, textured, and tan in appearance. Credit: NASA, ESA, and E.
