S/2007 S 2 is a
retrograde direction and with an eccentricity of 0.237.[4] According to Denk et al. (2018), it is presumably at high risk of colliding with Phoebe in the future.[3]
The moon was once considered
lost in 2007 as it was not seen since its discovery.[5][6] The moon was later recovered and announced in October 2019.[7][8]
