Jupiter moon paragraph
I notice that there is a paragraph that deals with moons of Jupiter. Should this be moved to the Jupiter article? Or is it better here for some reason? Most of the rest of the article deals with Earth's moon.

Latent Heat

Io, a moon of Jupiter, has puzzled evolutionists because of its extensive heat. According to old-earth beliefs, this moon should have cooled long ago.[19] In fact, Io is the most volcanically active object in all the solar system. Most observers consider that Io is older than it looks, because the volcanoes and their associated lava flows have erased the craters. But that cannot apply to Europa, which looks at least as "young" as does Io. Io's volcanism testifies to its tremendous internal heat. In fact, Io is radiating far more heat than tidal heating alone could generate. And yet no astronomer accepts radioactive decay as a significant source of Io's heat. Either Io has another, still-unknown source of heat, or else the present rate of heat outflow is unsustainable and temporary.
