The image was recorded using the Cassini's narrow-angle camera on Aug. 1, 2017 using filters that allow infrared, green, and ultraviolet light.
- The image filter centered on 930 nm (IR) was is red in this image,
- the image filter centered on the green is green, and
- the image filter centered on 338 nm (UV) is blue.
This image was obtained at a distance of approximately 112,000 miles from Enceladus. Image scale is about 0.6 mile per pixel. (Ciclops)
Earth's moon is about 250,000 miles away, so we (that's the royal 'we') were about half that distance from Enceladus. That moon is like two-thirds the diameter of Titan, or one sixth the diameter of Earth's moon. Put that all together and looking at Enceladus from Cassini, it will to be about one-third the size of the Earth's moon as seen from the Earth.
