1. There are several theories regarding the dark matter covering Iapetus' leading hemisphere: comet impact, volcanos, drift from the other moons, among others. This moon is brightest at the poles.
2. I like the little Phoebe moon. I like the idea of "captured asteroids."
3. I had a question about comet propulsion while the prof was lecturing, but I didn't ask. I'll have to look it up tonight when I'm here all by myself.
