S/2009 S 1

S/2009 S 1 is a embedded in the outer part of Saturn's B Ring orbiting 117,000 km away from the planet. The moonlet was discovered by the Cassini 
Imaging Team during the Saturnian equinox event on 26 July 2009, when the Cassini spacecraft imaged the moonlet casting a 36 km (22 mi)-long shadow onto the B Ring. With a diameter of 300 m (1,000 ft), it is most likely a long-lived solid body, which would count it as the smallest and innermost known moon of Saturn.
== Discovery ==
S/2009 S 1 was first identified by the Cassini Imaging Team led by Carolyn Porco, in a single image taken by the Cassini spacecraft approximately 296,000 km (184,000 mi) from Saturn on 26 July 2009 11:30 UTC. The moonlet was discovered during Saturn's 2009 equinox, when it cast an approximately 36 km (22 mi)-long shadow on the planet's B ring.
== Characteristics ==
Based on the width of its shadow it was estimated to be 300 m (~1000 ft) in diameter, making it one of the smallest moons in the Saturn System.
