Radius (estimated)
3.5 km
Sized from its brightness assuming a dark (~0.04) surface — never resolved, so the true diameter (~7 km) could be off by a factor of two.

Discovery & history

By
S. Sheppard, D.C. Jewitt, J. Kleyna

Bestla was discovered in 2004 by S. Sheppard 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.

No resolved image of this moon has been released: telescopes and passing spacecraft have recorded it only as a faint point of light.
