Logos is a
barycentre
on a moderately elliptical orbit.
Logos was discovered on 4 February 1997, and its, companion, Zoe, was discovered on 17 November 2001 from

After the discovery, it received the
provisional designation S/2001 (58534) 1. Once confirmed it was officially named (58534) Logos I Zoe. It orbits Logos with a semi-major axis of 8217 km in 309.9 days with an eccentricity of 0.546.[7] Its estimated diameter is 66 km,[5]
and mass (0.15 ± 0.02)×1018 kg.
