Question
When Cassini, a Saturn-orbiting spacecraft, made its first flybys of Enceladus in 2005, what unusual discovery did it make, and what did this imply?
a Enceladus turned out to have a system of rings around it, much like Saturn has, making it the first known moon with its own ring system.
b Saturn's magnetic field was disrupted near Enceladus, suggesting the tiny moon might have an atmosphere, which in turn suggested material might be emitted by Enceladus in some way.
c Cassini discovered that Enceladus is being constantly bombarded by asteroids and meteoroids, suggesting it has a much larger mass (and thus higher gravity) than had been suspected.
d Enceladus was orbiting Saturn much faster than it should, based on Kepler's laws, suggesting that some mysterious force was pushing it around its orbit.
