The earth is still stationary with respect to itself. The Universe is accelerating around it. In the case of Saturn's moons the Sun and Earth are not significant factors, if I use the Earth as my origin I have to account for those anyway, but if I were to use Saturn as my origin I could safely ignore them (probably - I could come up with sci-fi reasons that they matter). |
