−47.0°), as well as (115.0°, −77.0°) and (338.0°, −43.0°) in ecliptic coordinates (λ, β). Diameter and albedo According to the surveys carried out by the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer (WISE), Athene measures () and () kilometers in diameter and its surface has an albedo of () and (), respectively. The Collaborative Asteroid Lightcurve Link assumes a standard Eunomian albedo of 0.21 and calculates a diameter of 12.66 kilometers based on an absolute magnitude of 11.8. Alternative mean-diameter measurements published by the WISE team include (), () and () with corresponding albedos of (), () and ().
