Saturn's small satellites at 100 meters per pixel
Saturn's small satellites at 100 meters per pixel A comparison of the sizes of Saturn's smallest satellites as viewed by Cassini over the course of its 13-year mission. When fully enlarged, the comparison has a resolution of 100 meters per pixel. NASA / JPL-Caltech / SSI / Emily Lakdawalla. Satellite dimensions from Thomas et al (2013)

Here are two other comparisons at a factor of 5 finer and coarser resolutions, respectively.

Saturn's tiniest regular moons at 20 meters per pixel
Saturn's tiniest regular moons at 20 meters per pixel A comparison of the sizes of Saturn's very smallest regular satellites as viewed by Cassini over the course of its 13-year mission. When fully enlarged, the comparison has a resolution of 20 meters per pixel. Aegaeon, Anthe, Pallene, and Polydeuces are all represented by an image of Methone.Image: NASA / JPL-Caltech / SSI / Emily Lakdawalla. Satellite dimensions from Thomas et al. (2013)

Saturn's smaller satellites at 500 meters per pixel
Saturn's smaller satellites at 500 meters per pixel Above the size of Hyperion (upper left corner), Saturn's satellites abruptly transition to round shapes. When fully enlarged, this view has a resolution of 500 meters per pixel.Image: NASA / JPL-Caltech / SSI / Emily Lakdawalla. Satellite dimensions from Thomas (2010)
