cubewano . The object is notable for having a satellite, named Zoe.For a small (80km in diameter) KBO it has a very high
albedo .In the
Gnostic tradition,Logos andZoe are a paired emanation of the deity, and part of its creation myth.MPCit_MPES|58534Zoe
Logos' companion was discovered on
17 November ,2001 fromHubble Space Telescope observations by K. S. Noll, D. C. Stephens, W. M. Grundy, J. Spencer, R. L. Millis, M. W. Buie, D. Cruikshank, S. C. Tegler, and W. Romanishin and announced on11 February ,2002 .After the discovery, it received the
provisional designation S/2001 (58534) 1. Once confirmed it was officially named (58534) Logos I Zoe (pronEng|ˈzoʊiː, from _gr. "Ζωή"). It orbits Logos with a semi-major axis of 8010 ± 80 km in 312 ± 3 d with an eccentricity of 0.45 ± 0.03. Its estimated diameter is 66 km, and mass (0.15 ± 0.02)e|18 kg.Orbit
