Correio da Cassini
Cassini continues to uncover new wonders within the Saturn system with its discovery of two new moons orbiting between Mimas and Enceladus. This movie shows the tiny "worldlet," temporarily dubbed S/2004 S2, as it makes its way around the planet. A white box frames the moon's location in the image. The image is part of a sequence specifically designed to search for new moons in the inner saturnian system. The image has not been cleaned of imaging artifacts but has been greatly enhanced in contrast to increase visibility. Consequently, the background scattered light from the nearby rings, as well as many cosmic ray hits and noise patterns, are clearly apparent. The size of S/2004 S2 is estimated to be 4 kilometers (about 2.5 miles) across. Because the moon is small and not resolved it appears as a faint point of light just barely visible above the background.
