2.80 Earth years
Science
Physical
- Radius (estimated)
- 2 km
- Sized from its brightness assuming a dark (~0.04) surface — never resolved, so the true diameter (~4 km) could be off by a factor of two.
Orbit around Saturn
- Distance from Saturn
- 0.131 AU
- From JPL orbital elements
- Orbital period
- 2.80 years
- From JPL orbital elements
- Eccentricity
- 0.581
- From JPL orbital elements
- Inclination to the J2000 equator
- 159.06 °
- From JPL orbital elements
Radiation & temperature
- Insolation
- 0.0113 S⊕ · 1% of the sunlight Earth receives
- Computed from the distance to the Sun (inverse-square; Earth's sunlight = 1), before any atmosphere.
Discovery & history

- D.C. Jewitt, S.S. Sheppard, J. Kleyna, E.J. Ashton, B.J. Gladman, J.-M. Petit, M. Alexandersen
S/2004 S 45 is the provisional designation of a small moon of Saturn detected in 2004 by D.C. Jewitt and colleagues. It has not yet been given a permanent name, and little is known about it beyond its discovery and orbit.
