Science
Physical
- Radius (estimated)
- 19.6 km · 1% of our Moon's radius
- Sized from its brightness assuming a dark (~0.04) surface — never resolved, so the true diameter (~39.3 km) could be off by a factor of two.
Orbit around Saturn
- Distance from Saturn

- 0.4618
- From JPL orbital elements
- Inclination to the J2000 equator

Radiation & temperature
- Insolation
- 0.0112 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

- B. Gladman, J. Kavelaars, J.-M. Petit, H. Scholl, M. Holman, B.G. Marsden, P. Nicholson, J.A. Burns
Siarnaq was discovered in 2000 by B. Gladman and colleagues. Saturn's moons are named after giants and deities of world mythology — its distant irregular moons after Norse, Inuit and Gallic figures. Beyond its discovery and naming, little more about it has been individually recorded.
