[3] Leocadia is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbital elements.
All of these low-numbered asteroids have numbers between 164 Eva and 1514 Ricouxa and were discovered between 1876 and the 1930s, predominantly by astronomers Auguste Charlois, Johann Palisa, Max Wolf and Karl Reinmuth.
[12] In the Tholen classification (FXU:), Leocadia is an uncommon and dark F-type asteroid, somewhat similar to that of an X-type, though with an unusual (U) and noisy (:) spectra.
Lightcurve analysis gave a rotation period of 6.87±0.01 hours with a brightness amplitude of 0.14±0.01 magnitude (U=2), which is indicative of a rather spherical, non-irregular shape.
[11] The Collaborative Asteroid Lightcurve Link adopts the result from IRAS, that is, an albedo of 0.0435 and a diameter of 19.51 kilometers based on an absolute magnitude of 9.22.
