Wave At Saturn
I simulated what it would look like from Cassini’s point of view using Celestia. In the second image, the distance from Saturn is about 160,000km away, which is fairly close compared to where it is now. The last image is more realistic as this is about where Cassini orbits Saturn (around 1,110,000km away) and the Sun would have been eclipsed by Saturn at the time. You can see Earth highlighted with the red cross-hairs to the right, 1,445,858,030 kilometers away.
