If viewed from the surface of Titan, would Saturn appear to have phases like Earth's moon?
Interesting question actually, in fact I didn't know that Titan was tidally locked to Saturn. Still, let's think about this, Titan is still orbiting Saturn. And if you visualize it, the only way a moon could orbit a planet without the planet having phases would be if the Moon was orbiting exactly perpendicular to the planet's orbit around the Sun, and maintained that orientation as the Planet orbited its sun. That seems really unlikely, so from Titan Saturn must have phases. In fact I guess the phases would be synced to Titan's orbit around Saturn.
