Factual error: Jonah tells Richard that Saturn has a "rogue moon" in a retrograde orbit that travels "at four times the speed" of Saturn's other moons. The graphic on Jonah's computer shows that the moon in question is Phoebe, which does indeed orbit in the opposite direction from other Saturnian moons. And the graphic correctly shows Phoebe's orbit as being much further from the planet than the other moons. However, as a direct consequence of its greater orbital radius, Phoebe is actually among Saturn's *slowest* moons. It has a longer orbital period (or "month") and a slower orbital velocity than all the Saturnian moons with smaller orbital radii, of which there are twenty.
Sister Josepha Montefiore: "Father, why hast thou forsaken me?" Christ asked the same question.
Richard: Did he get an answer?
Sister Josepha Montefiore: Well, he wasn't a scientist so he knew that... some questions have none.
