The largest planet in our solar system represents a gap between the cluster of planets closest to the sun and those beyond. At 5.2 miles from our model sun on our astro-scavenger hunt, we’re finally getting some size. This one’s a bit wider than a five-foot arm span – it’s 61.4 inches – like a really big beach ball. And its four largest moons are Io, 1.6 inches; Europa, 1.3; Ganymede, 2.3; and Callisto, 2.1.
Remember, this is a scale of one to 93 million. As inconceivable as that seems.
