Marsden on May 1, 2007 from observations taken between January 18 and April 19, 2007. S/2007 S 3 is about 5 kilometres in diameter, and orbits Saturn at an average distance of 20,518,500 kilometres in about 1100 days, at an inclination of 177.22° to the ecliptic, in a retrograde direction and with an eccentricity of 0.130. This moon has not been seen since its discovery in 2007 and is currently considered lost.[1][2][3] References1. ^{{cite web |url=http://www.skyandtelescope.com/astronomy-news/outer-planet-moons-found-and-lost/ |title=Outer-Planet Moons Found — and Lost |last=Beatty |first=Kelly |date=4 April 2012 |website=www.skyandtelescope.com |publisher=Sky & Telescope |access-date=27 June 2017}} 2. ^{{cite journal |last1=Brozović |first1=Marina |last2=Jacobson |first2=Robert A. |date=9 March 2017 |title=The Orbits of Jupiter's Irregular Satellites |journal=The Astronomical Journal |volume=153 |issue=4 |pages=147 |doi=10.3847/1538-3881/aa5e4d|bibcode = 2017AJ....153..147B }} 3. ^{{cite journal |last1=Jacobson |first1=B. |last2=Brozović |first2=M. |first3=B. |last3=Gladman |first4=M. |last4=Alexandersen |first5=P.
