That's no moon. It's a space station

By Eric Hartwell, January 11, 2008

Consider the following:

Just to be clear, the object at the left definitely is a moon. It's Saturn's moon Epimetheus, which has a diameter of 116 km. The larger object at right, definitely not a moon, has an estimated diameter of 120-160km. You can see how a novice Jedi might make that mistake from a distance.

Luke: He's headed for that small moon.

Ben: That's no moon. It's a space station.

Han: It's too big to be a space station.

Luke: I have a very bad feeling about this.
