58534 Logos, or as a binary system (58534) Logos-Zoe,[7] is a trans-Neptunian object and binary system from the classical Kuiper belt, approximately 77 kilometers (48 miles) in diameter. The bright cubewano belongs to the cold population and has a 66-kilometer (41 miles) sized companion named Zoe.[6] The system mass is (4.58±0.07)×1017 kg.[7]
In the Gnostic tradition, Logos and Zoe are a paired emanation of the deity, and part of its creation myth.[1]
