Orbits between Mimas and Enceladaus.
 
Originally named S/2004 S1.
 
No disk-resolved images of any of the new satellites have yet been taken.
Size estimates have been made by assuming appropriate disk-integrated
reflectivities and taking into account the solar phase angle and the
pixel size in kilometers to compute observed I/F values and subsequently
derive a surface area. This calculation yielded approximate diameters of
3 km.
Methone, very close to Mimas's region of influence, might be
expected to have a substantial eccentricity and inclination, yet it does
not.
