NotesGalatea is a 'rubble pile' moon, a loose mass of material held together by gravitational forces. It pursues a close orbit of Neptune, just within the Adams Ring, the faint outer ring of Neptune. Indeed, Galatea appears to act as a shepherd moon for this ring, helping to define and maintain its structure.
