D) Other newly discovered satellites (S/2004 S7 to S10 and S12 to S18) have `negative’ orbits and orbital inclination from 147.4 to 168.

The exceptions are:

1) Bebhionn (S/2004 S11) ~3 17,120 835 ND 35

2) Daphnis (S/2005 S1) 4.3x4.1x3.2 136.5 0.594 ND 0

As noted above, both have normal orbital parameters and low orbital inclination.

S=Synchronous rotation = (rotation period is the same as the orbital period), R=Retrograde motion (orbit),

ND=No data available, C= Chaotic motion.
