Wide-field Infrared Survey Explorer (WISE), Faïna measures (), () and () kilometers in diameter and its surface has a low albedo of (), () and (), respectively. The Collaborative Asteroid Lightcurve Link adopts the results from IRAS, that is, an albedo of 0.0497 and a diameter of 110.50 kilometers based on an absolute magnitude of 8.66. The WISE team also published several alternative mean-diameters of (), (), (), () and (), with a corresponding albedo of (), (), (), (), and (). On 28 March 2007, an asteroid occultation of Faïna gave a best-fit ellipse dimension of () with a quality rating of 2, indicating its irregular, elongated shape. Another occultation on 21 October 2012, gave an ellipse of (). These timed observations are taken when the asteroid passes in front of a distant star.
