    Regarding the Galilean moons (Ganymed, Callisto, Europa and IO), are they all on the same orbital plane? (I.E...Jupiters equator)

    Was looking at them tonight through my telescope and I can see all 4 of them, but a strait line would not connect with all 4 of them. Cant think of any other simple explanation myself.

    Maybe its an angle thing. Twice every 30 years Saturns rings appear edge on to us, and therefore it appears Saturn has no rings. Jupiter is perpendicular to the plane of the solar system, but Earth orbits the sun at about 24 degrees. Maybe this is enough to create visual discrepancies such as what I described? F**** im pissed.

    I think you mean astronomical.
    The tilt of the Earth wouldn't change anything. The tilt of Jupiter could, but since that's close to 0 it doesn't matter. What matters is that the Galilean moons have different orbital inclinations, so will rarely form a line.
