Logos is a binary with the components of comparable size orbiting the barycentre on a moderately elliptical orbit.
Logos was discovered on 4 February 1997, and its, companion, Zoe, was discovered on 17 November 2001 from Hubble Space Telescope observations by K. S. Noll, D. C. Stephens, W. M. Grundy, J. Spencer, Robert Millis, Marc Buie, Dale Cruikshank, S. C. Tegler, and W. Romanishin and announced on 11 February 2002.
After the discovery, it received the provisional designation . 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. Its estimated diameter is 66 km, and mass (0.15 ± 0.02) kg.
A 10-million-year integration of the orbit shows that it is a Classical Kuiper belt object that does not get closer to the Sun than 38.8abbr=unitNaNabbr=unit or further than 52.1 AU.
