[2][3] Toni is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbital elements.
[4][6] In July 2014, a rotational lightcurve of Toni was obtained from photometric observations by Frederick Pilcher at the Organ Mesa Observatory (G50) in New Mexico.
[10] This result supersedes previous observations with tentative period determinations by French amateur astronomers René Roy and Laurent Bernasconi (U=1/1).
[12] According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer (WISE), the Japanese Akari satellite, and the Infrared Astronomical Satellite IRAS, Toni measures (71.983±25.283), (78.33±1.34) and (85.49±2.5) kilometers in diameter and its surface has a low albedo of (0.052±0.007), (0.054±0.002) and (0.0432±0.003), respectively.
[6][7][8][9] The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, an albedo of 0.0432 and a diameter of 85.49 km based on an absolute magnitude of 9.37.
