54598 Bienor (/bᵻ.ˈiːnɔːr/ bi-YEE-nor; from Greek: Βιάνωρ Bianor) is a centaur that grazes the orbit of Uranus. It is named after the mythological Centaur Bienor. Its closest approach to the Sun (perihelion) is 13.2 AU.^[2] As of 2015^[update], Bienor is currently 15.8 AU from the Sun^[3] and will reach perihelion in January 2028.^[2]
