    With the naked eye you can see Mercury, Venus, Earth(!), Mars, Jupiter, Saturn, and if you're lucky Uranus.

    With good conditions, you can also see Vesta, the second biggest object in the asteroid belt.

    • If you can see Vesta, can't you also see Ceres?

    • Vesta has a higher albedo, and is closer.

    • Ah, I see.

    • If the brightness of Jupiter didn't overwhelm them I believe the four largest moons of that planet could also be spotted.

    • From this distance, assuming you could seen those moons, I don't think that the angular separation would be great enough to be able to distinguish them from the planet with the unaided eye.

    • Thanks for that caveat, that's more or less what I meant by the 'brightness' of Jupiter overwhelming them. If you removed Jupiter, you would be able to view them individually (providing they were not too close to each other in angular measurement). Perhaps you could only see each one, one at a time on it's own!

    • That's my point. Even if Jupiter were invisible, I don't think that the Galilean Satellites are far enough apart for us to see them as individual points with the unaided eye from here.

    • Would we then see them as one point of light?

    • That is what I would expect. I am not entirely certain of this, but that is what I would expect.
