During the four hours it took Cassini to image the entire 647,808 kilometres (402,529 mi)-wide scene, the spacecraft captured a total of 323 images, 141 of which were used in the mosaic. [6] NASA revealed that this imaging marked the first time four planets – Saturn, Earth, Mars, and Venus – had been captured at once in visible light by the ...
