In the Gnostic tradition, Logos and Zoe are a paired emanation of the deity, and part of its creation myth. ==Zoe== Logos is a binary with the components of comparable size orbiting the barycentre on a moderately elliptical orbit. Logos' companion was discovered on 17 November 2001 from Hubble 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.

Once confirmed it was officially named (58534) Logos I Zoe (; from (ギリシア語:''Ζωή'')). It orbits Logos with a semi-major axis of 8217 ± 42 km in 309.9 ± 0.2 d with an eccentricity of 0.546 ± 0.008.〔 Its estimated diameter is 66 km, and mass (0.15 ± 0.02) kg. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「58534 Logos」の詳細全文を読む スポンサード リンク
