This Voyager 1 mosaic principally consists of 3 color composites made of orange-, green-, and blue-filtered images, all taken with the wide-angle camera on 4 March 1979. Gaps in coverage were filled by other 3-filter composites taken earlier or later the same day. North is to the right. Planet-spacecraft distance was some 1 million km. NASA / JPL / Ian Regan
