S/2009 S 1
The bright dot with a long shadow in the center is S/2009 S1. The Cassini Division is on the right.
S/2009 S 1 is a 'propeller moonlet' of Saturn orbiting at a distance of about 117,000 kilometres (73,000 mi), in the outer part of Saturn's B Ring, and with an approximate diameter of 400 meters (1,300 ft).[1] It was discovered by the Cassini Imaging Team[2] on July 26, 2009. The moon was noticed during the 2009 equinox event by an approximately 36 kilometres (22 mi) long shadow which it cast on Saturn's B ring. S/2009 S 1 protrudes approximately 150 metres (490 ft) above the ring.[3] The image was taken about 296,000 kilometres (184,000 mi) from Saturn.[1]
