From Brightest to Dimmest:
Ganymede
Io
Europa
Callisto
Use JPL's HORIZONS web ephemeris to look up apparent magnitudes of jovian satellites.
Io Europa Ganymede Callisto
i believe that it is Io, Europa, Ganymede then Callisto. This is in order of brightness seen from Jupiter's surface.
Europa is one of Jupiter's moons. Actally theres Europa, Callisto, Ganymade, and Io. :] Ganymede, Io, Europa and Callisto Jupiter has 67 moons, of which four are major. Those moons are Io, Europa, Ganymede, and Callisto.
Io, Europa, Ganymede and Callisto are the four satellites that orbit Jupiter.
From Earth they're pretty similar, in fact, I can't even tell their brightness apart through binoculars. You can see them for yourself with a pair of binoculars and something to rest them against. But going by the magnitude scale, Callisto's the brightest. Io 5.5 Europa 5.7 Ganymede 5.1 Callisto 6.1
