Greip retrograde direction and with an eccentricity of 0.3735, and is presumably at high risk of eventually colliding with Phoebe.[3] It is unknown whether Greip is more similar to Suttungr or Hyrrokkin in color.[3] Its rotation period is most likely 12.75±0.35 hours with two minima in the light curve,[2] but a longer period of 19 hours cannot be ruled out due to the short observation time by Cassini–Huygens.[3]
It is named after Greip, a giantess in Norse mythology.
